- Graphite Crucible For Melting Precious Metals
Graphite crucible for melting precious metals are made from high quality bonded graphite and pre-grade materials and are designed to handle temperatures at 2900 °F
Graphite crucible for melting precious metals are made from high quality bonded graphite and pre-grade materials and are designed to handle temperatures at 2900 °F and are therefore capable of handling intense direct heat from open flame bases and high frequency induction furnaces. They are used to melt precious metals, iron and non-ferrous alloys, considering that they are cleaner than our standard crosses. High fire resistance, good chemical resistance, and available in a variety of sizes!
