Feature:1. Electrical Conductivity: Our melting ingot has thermal shock resistance, electrical conductivity and thermal conductivity, which can smelt metals well.2. Wear Resistance: Our ingot mold has good wear resistance, strong lubricating properties and durability. It also has long service life, and can be used for a long time, so you are satisfied.3. High Density: Our graphite ingot mold has high purity, high density, high mechanical strength and strong chemical stability, so in the process of metal smelting, there will be no chemical reaction with the metal.4. Lubricity: The surface of our graphite crucible can be treated with anti oxidation. It has high purity, high mechanical strength and good lubricity, so it is more convenient for metal smelting.5. Applicable: Our casting ingot mold can be used for smelting precious metals such as gold and silver, so they are very suitable for smelting metals in various factories.Specification:Item Type: Ingot casting toolMaterial: GraphiteOuter Size Of Disc: Approx. 50 x 13mm / 2 x 0.5in (diameter x height)Inner Size Of Disc: Approx. 40 x 8mm / 1.6 x 0.3in (diameter x depth).Package List:1 x Ingot Casting Tool
