Ingot Mold Fused Gold 141.1 Oz High Purity Corrosion Resistant External 100*100*50MM Inner

Feature: 1. GOOD STABILITY: This pure graphite crucible improves metal melting efficiency, has high stability performance and good thermal conductivity, and can greatly reduce melting and molding time. Gold casting capacity is 4000g. 2. HIGH STRENGTH: The melting crucible has high mechanical strength, good chemical stability, good wear resistance, strong lubricating properties, long service life, high purity and high density. 3. PURE GRAPHITE: Crucible is made of high purity graphite to ensure that metals in casting are not contaminated. Graphite casting crucibles are designed for melting gold, silver, copper, brass, aluminum, etc. 4. INTERNAL SMOOTHNESS: The inner wall of graphite crucible is smooth, and the metal liquid is not easy to leak and adhere to the inner wall of the crucible, so that the metal liquid has good fluidity and castability. 5. NOTE: The graphite crucible should not be placed on a cold metal table immediately after heating to avoid it breaking due to rapid cooling.
