3KG High Purity Melting Graphite Crucible for Gold Silver Metal Smelting Tools Description The high density of graphite crucible makes the crucible have good thermal conductivity. It is used in electric melting furnace for melting copper, gold, aluminum, silver, precious metal etc. 1. The use temperature is less than or equal to 1800 ℃, can be used to melt gold, silver, copper, aluminum, iron and other precious metal 2. Good thermal and shock resistance. Good thermal conductivity. Fast heating speed 3. The high density of graphite crucible makes the crucible have good thermal conductivity 4. The surface of the graphite crucible has a special glaze layer and dense molding material, which greatly improves the corrosion resistance of the product and extends its service life 5.3KG capacity: 3KG copper can be holded. 6.4KG gold, 3.5KG silver, 0.9KG aluminum Note: The graphite crucible will hold different metal weight according to the different density of metal material. Weight (kg)=Density(kg/m³) *Volume(m³) Specification Name: Graphite crucible Model: 3KG Material: graphite Operating temperature: ≤1800℃ Capacity:3KG Product Size:φ75mm&φ60mm*170mm Package included: 1x Crucible
