- Premium Material: Grooved graphite crucibles are crafted from natural graphite, offering excellent thermal conductivity and high-temperature endurance with minimal thermal expansion during high-temperature use. Specifically engineered for easy removal of scrap metal from furnaces
- Industrial-Grade Design: Metal melting ingot molds feature deeper grooves for safe removal from the furnace with zero metal adhesion—conserving precious alloys and eliminating material waste in gold, silver, and copper casting
- Large-Capacity Smelting: Our graphite crucible smelting tools feature a 3 kg (334 ml) capacity, capable of melting up to 6.4 kg of gold, 3.5 kg of silver, 3 kg of copper, or 0.9 kg of aluminum. Ready for vacuum or gas furnaces, they withstand temperatures up to 5000°F (2760°C). For electric furnace use, they remain stable at 3200°F (1760°C). Ideal for platinum smelting and high-alloy casting
- Long-term use: High-purity graphite crucibles feature a special glaze layer and dense forming material, significantly improving endurance to slag erosion and metal oxidation while extending service life
- Important Note: Preheat 3 kg graphite crucibles before use to prevent thermal shock. Do not heat in carbon furnaces or kilns, as oxidation and cracking will occur. Operating temperature ≤ 1800°C. Suitable for smelting gold, silver, platinum, and other precious metals, as well as metallurgical processing and metal casting
