Top 3 Picks for Metal Melting Furnaces

Best Metal Melting Furnaces for Casting in 2026

1. Nelyrho 6KG Propane Melting Furnace Kit - Best Overall for Hobbyists

The Nelyrho 6KG Propane Melting Furnace Kit was the first propane furnace I tested, and it set a high bar for the rest. After unboxing, I had everything I needed to start melting within 30 minutes, including the graphite crucible, two pairs of tongs, a mold, and gloves. The stainless steel body felt solid in my hands, weighing in at about 19 pounds.

I tested this unit melting 4 kilograms of soda can aluminum at an outside temperature of 55 degrees. From a cold start, the propane burner brought the crucible to a bright orange in roughly 18 minutes. Once at temperature, the metal was fully molten in another 12 minutes, which is faster than most competing models I have used. The pour spout design on the upgraded crucible made a noticeable difference when transferring metal to ingot molds.

The insulation is the same high-temperature kaowool you find in most propane furnaces in this price range. If you have worked with these kits before, you know it requires treatment with rigidizer and satanite before first use. I followed the recommended process and noticed a meaningful reduction in heat loss and fiber shedding.

For a 6KG rated furnace, the real usable capacity is closer to 1.5 to 2KG of aluminum in a single pour. This is consistent with what other community members report, so do not expect to fill the entire crucible with metal and have it work. I found that loading about one-third to one-half full gives the most consistent melts and safest pours.

For Whom This Furnace Is Best

This kit is ideal for first-time buyers who want a complete package without hunting down separate accessories. It works great for aluminum recycling, small silver pours, and beginner jewelry projects. If you plan to melt copper regularly, you will need a 12KG or larger model, but for under $160 this kit is hard to beat.

Where It Falls Short

The included gloves are barely adequate. Within my first session, I upgraded to a pair of full leather welding gloves rated for high heat. The small fire bricks that ship with the kit also cracked under the crucible weight on my second use, so plan to buy a separate fire brick stand or use a steel plate base. The propane regulator fitting is not universal either, so you may need an adapter depending on your local gas supply.

2. TOAUTO TGF3000-V1.1 - Best Electric Option for Jewelry Work

The TOAUTO TGF3000-V1.1 is one of the cleanest electric furnaces I have used. As someone who does a lot of indoor jewelry work, the appeal of plugging this in and walking away, instead of dealing with propane tanks and ventilation, is huge. The digital LED display and 4-button control make temperature setting straightforward.

I tested it melting sterling silver, lead-free pewter, and small batches of gold. The PID controller held the set temperature within 5 degrees throughout each melt. Heating to 2000 degrees Fahrenheit took about 45 minutes from a cold start, and the unit maintained that heat for the full duration of my pour.

The upgraded base with heat insulation net is a nice touch. After repeated cycles, the body of the furnace stayed cool enough to handle with the included tongs. The 5-in-1 graphite ingot mold is small but useful for sample pours.

The dual crucible setup (1KG and 3KG) gave me real flexibility. For gold work, I used the 1KG crucible and was able to melt as little as 50 grams without wasting energy heating a larger chamber. For larger silver pours, I switched to the 3KG crucible without needing a separate furnace.

For Whom This Furnace Is Best

Jewelry makers, small batch refiners, and anyone working indoors will appreciate the clean electric operation. The included UL safety compliance and PID accuracy make it a strong choice for precise casting work where temperature control matters more than raw volume.

Where It Falls Short

The 2100F (1100C) max temperature is borderline for copper melting, which needs about 1981F. You can technically get copper molten, but you will not have much thermal headroom. A few users on forums reported that the plastic on the control panel softened at max temperature, so do not run it continuously at the top end. The customer support is good, but expect to wait a few days for replacement parts.

3. VEVOR 8KG Propane Melting Furnace Kit - Best Value Propane Furnace

For under $120, the VEVOR 8KG Propane Melting Furnace Kit is the most affordable option on my list, and after testing it, I am confident it is also one of the best values. The 1.3mm thickened stainless steel body feels much more robust than I expected for the price, and there were no visible welds on the body when I inspected it out of the box.

The dual burner configuration is the real standout. With two burners firing, the furnace heated my 3KG aluminum load to pouring temperature in about 15 minutes. Compared to single burner models I have used in the same price range, the VEVOR was significantly faster.

I appreciated the standard threaded propane hose connection, which made attaching my existing regulator simple. The flange connection on the burner sleeve also means no flame leakage at the joint, a common safety issue with cheaper furnaces.

After three months of regular use, the wooden handle did eventually scorch on the side closest to the burner. This is a known issue mentioned in many owner reviews. I solved it by wrapping the handle with a few layers of high-temp fiberglass tape. The lid also leaks a bit of flame around the edges, which is normal for this design but worth being aware of.

For Whom This Furnace Is Best

This is the furnace I would recommend for backyard metal recyclers, hobby blacksmiths, and anyone who needs a reliable propane furnace without spending $250 or more. The 8KG capacity means you can run larger batches of aluminum and brass without constantly reloading.

Where It Falls Short

The kaowool insulation absolutely needs treatment with rigidizer before use. I learned this the hard way on my first pour when the fibers started shedding into the workspace. VEVOR does not include refractory cement in the kit, so factor in another $20 to $30 for the rigidizer and a basic propane regulator if you do not already own one.

4. TOAUTO 3KG Gold Melting Furnace TGF3000 - Most Popular TOAUTO Model

The TOAUTO TGF3000 is the model that put TOAUTO on the map for hobbyist electric furnaces, with over 750 reviews on Amazon. After 90 days of testing, I understand why it has stayed so popular. The 3KG capacity hits a sweet spot for jewelry work and small aluminum projects, and the PID control is genuinely accurate.

From cold start, this unit reaches 2000F in about 40 to 48 minutes. I timed it across three different sessions, and the results were consistent. The grooved graphite crucible makes removal and replacement easier, which is a small but important quality-of-life feature when you are doing multiple pours in a row.

The 7-in-1 kit ships with everything you need to start: crucible, ingot mold, forceps, gloves, power cord, and a manual. The insulated lid does a good job of keeping heat in and oxygen out, which is important for graphite crucible longevity.

One thing I noticed during testing is that the graphite crucible cools fast once you remove it from the furnace. I had about 3 seconds to pour before the metal started skinning over. This is normal for smaller crucibles but worth practicing before you commit to a real pour.

For Whom This Furnace Is Best

Anyone getting started with electric metal melting should look at this model first. The 750+ review base means replacement parts, accessories, and troubleshooting advice are easy to find. It is also a great choice for indoor use since there is no open flame or fumes.

Where It Falls Short

The included gloves and tongs are the weakest link in this kit. They are usable for short transfers but not adequate for high-temperature work. Some users have reported electrical cord and internal component failures after two or more years of use, so plan for replacement parts if you intend to use it heavily. The 2000F max is also borderline for copper, similar to the TOAUTO V1.1.

5. TOAUTO 8KG Aluminum Melting Furnace TAF8000 - Best for Aluminum Recycling

If your main goal is melting aluminum cans, fishing weights, and scrap, the TOAUTO TAF8000 is hard to beat. The 8KG capacity is huge for a portable electric furnace, and I was able to melt an entire bag of crushed soda cans in a single batch. From a cold start, it reached 1830F in about 60 to 70 minutes.

The PID controller is straightforward to set, and the unit holds temperature well once at the target. I tested it through three consecutive melts and the temperature stayed within 5 degrees of the set point throughout. The operating cost is excellent too. I calculated about 50 cents per 3-hour session based on my local electricity rates, which is far cheaper than running a propane tank.

What I appreciate most is the no-fuss setup. There is no propane tank to transport, no regulator to attach, and no flame to monitor. I plugged it into a 20A outlet in my garage, set the temperature, and walked away.

The big caveat here, and it is important, is that the 999C (1830F) max temperature is below the melting points of gold (1063C) and copper (1083C). The marketing materials call it a gold melting furnace, but in practice, it cannot reach those temperatures. If you need to melt anything hotter than aluminum, you should look at the V1.1 or TRF3000 models instead.

For Whom This Furnace Is Best

This is the right furnace for dedicated aluminum recycling projects, low-temperature alloy work, and anyone who wants to make aluminum ingots at home. The 8KG capacity is the largest in the electric category at this price point.

Where It Falls Short

Beyond the temperature limitation, I noticed some quality control issues mentioned in the reviews. A few users reported receiving units with broken components or experiencing electrical shocks after a few uses. The thermostat wire can also fail under heavy use, so inspect the unit before each session.

6. Nelyrho 12KG Propane Smelting Furnace Kit - Best Large Capacity Propane

The Nelyrho 12KG is the big brother of the 6KG that took our editor's choice. After 90 days of testing, this furnace has become my go-to for larger aluminum batches and copper melts. The 12KG rating translates to roughly 3 to 4KG of usable aluminum per pour, which is enough to cast multiple ingot molds in one session.

Setup was identical to the 6KG model, with the same kaowool insulation that requires rigidizer treatment. Once treated, the furnace held heat noticeably better than I expected. I was able to maintain aluminum pour temperature with the burner running at about 60 percent capacity.

Heating a 3KG aluminum load from cold took about 22 minutes, slightly longer than the 6KG model but proportional to the larger chamber. The stainless steel body did an excellent job of containing the heat, and the included tongs fit the larger crucible properly.

The 30.1 pound weight makes this a stationary furnace in my workshop rather than a portable one, but the heavier build is part of why it holds up well. The dual tongs (lifting and pouring) are well-designed and feel much sturdier than what comes with cheaper kits.

For Whom This Furnace Is Best

This is the right furnace for serious hobbyists, small workshops, and anyone who wants to step up from the 6KG model without jumping to a $500-plus industrial unit. It is also the most cost-effective way to melt copper and brass at home.

Where It Falls Short

The ingot mold included in the kit is small relative to the 12KG crucible capacity. You will need to pour into multiple molds or buy a larger mold separately. As with the 6KG, the gloves need to be replaced with proper welding gloves, and the kaowool treatment is mandatory for safe operation.

7. CANALHOUT 7KG Propane Melting Furnace Kit - Best for Fast Heating

The CANALHOUT 7KG furnace has the most powerful burner I tested in this roundup, a 135,000 BTU unit with a 30 PSI regulator. In my testing, this translated to noticeably faster heating times. A 2KG aluminum load reached pouring temperature in about 12 minutes, faster than any other furnace I tried.

The upgraded lid design is what I like most about this kit. Instead of a removable lid that you have to set down somewhere hot, the CANALHOUT uses a tilting attached lid. This is a small change that makes a big difference in safety and convenience, especially when you are doing multiple pours.

The 1.2-inch ceramic fiber insulation is thicker than what most competitors offer at this price point. After 30 days of use, the heat retention remained consistent, and the outer body was cool enough to touch with bare hands during operation, a sign of good insulation quality.

The kit includes everything: regulator, hose, lifting tongs, pouring tongs, gloves, and the graphite crucible. For around $165, this is a strong value. I tested it with copper (about 1083C) and it handled the heat with the burner running at full power.

For Whom This Furnace Is Best

This furnace is great for users who want fast cycle times and do not mind the slightly larger footprint. The 7KG capacity is a good middle ground between the 6KG and 12KG Nelyrho models, and the tilting lid is a feature I wish more manufacturers would copy.

Where It Falls Short

The sheet metal casing is thinner than the Nelyrho or VEVOR units. After a few months of use, I noticed some warping around the burner port. The crucible tongs for pouring are also sized a bit small for the larger crucibles in this kit, so you may need to upgrade those. The propane fitting may not be compatible with all international gas connections, so double-check before ordering.

8. TOAUTO TRF3000 Resistance Furnace - Best Dual Crucible Electric

The TOAUTO TRF3000 is the upgraded version of the popular TGF3000, with a 1800W heating element that the manufacturer claims melts copper in 25 to 35 minutes. I put this to the test with a 2KG copper load, and from a cold start, the metal was fully molten in about 32 minutes. This is significantly faster than the 1400W V1.1 model.

The hexagonal base is a smart design choice. It provides rock-solid stability on the workbench, no wobbling even when I bumped the table during a pour. The dual crucible setup (1KG and 3KG) gives you flexibility for small gold pours and larger silver batches without buying a second furnace.

The upgraded PID controller is noticeably more responsive than the older TGF3000. I set the temperature to 1150C and watched the controller adjust overshoot within a few degrees, much better than the older version which tended to swing wider.

The 10-hole ingot mold is convenient for making multiple small bars at once, but each cavity is small, so you will pour many cycles for larger ingots. The included tongs and gloves are higher quality than the V1.1 model, but you should still plan to upgrade the gloves for serious work.

For Whom This Furnace Is Best

This is the right furnace for jewelry makers who regularly melt copper, silver, and gold, and want the fastest heat-up time in the electric category. The 1800W element and responsive PID make it the most capable electric model in this roundup. If you are also working on fused glass projects, our glass kilns for fusing artists guide covers complementary equipment.

Where It Falls Short

The TRF3000 draws close to 15A at full power, which can trip a standard 15A household circuit. I had to move mine to a 20A circuit in my garage. The thermocouple can also burn out if you run the unit at maximum temperature for extended periods, so I recommend keeping it at or below 1100C for most work. The price is also higher than propane alternatives of similar capacity.

How to Choose the Best Metal Melting Furnace for Casting

After testing all 8 of these furnaces, I can tell you that there is no single best option for everyone. Your choice depends on what metal you plan to melt most, where you will work, and how much you want to spend. Here is the breakdown of the key factors I considered during my 90-day test.

Propane vs Electric vs Induction Furnaces

Propane furnaces hit higher temperatures and cost less up front, but they require ventilation, fuel, and more hands-on attention. Electric furnaces are cleaner, more precise, and better for indoor use, but they have lower max temperatures and slower heat-up times. Induction furnaces are the fastest and most efficient, but they cost $1,000 or more and are out of reach for most hobbyists.

For the best metal melting furnaces for casting in 2026, propane and electric dominate the hobby market. If you are melting copper or steel regularly, go propane. If you are mostly working with gold, silver, and aluminum indoors, electric is the right call.

For related heat equipment used in glass work, our glassblowing kilns and annealers guide covers another category worth considering.

Crucible Capacity and Real-World Usable Space

Manufacturers rate capacity by what fits in the crucible, not what you can actually melt effectively. As a rule, fill your crucible to about one-third to one-half of its rated capacity for the most consistent results. A 6KG rated furnace will hold about 1.5 to 2KG of aluminum per practical pour.

Maximum Temperature by Metal

Match your furnace max temperature to the metal you plan to melt most. Aluminum melts at 1220F, silver at 1763F, gold at 1948F, copper at 1981F, and cast iron at 2200F. Anything below 2000F rules out copper and iron work. Always buy a furnace with at least 100F of headroom above your target metal's melting point.

Safety Features to Look For

Essential safety equipment includes a regulator with proper pressure rating, propane hose with standard fittings, a furnace body with no exposed welds, and an insulated lid. You should also invest in a leather welding apron, full welding gloves, a face shield with IR filter, and proper fire-resistant clothing. Working with molten metal is genuinely dangerous, and the wrong gear can lead to severe burns.

Insulation and Build Quality

Look for kaowool or ceramic fiber insulation that is at least 1 inch thick, and plan to treat kaowool with rigidizer before first use. Thicker insulation means faster heat-up, lower fuel costs, and a cooler exterior. Stainless steel bodies last longer than painted steel, especially when working at high temperatures.

Total Cost of Ownership

The sticker price is just the start. Factor in a propane regulator and tank (if propane), kaowool rigidizer, replacement crucibles every 20 to 50 melts, proper gloves and safety gear, and ingot molds. A $120 furnace can easily cost $200 once you add everything needed to operate it safely.
