The Silicon Carbide Graphite (SiC Graphite) Crucible stands as the premier refractory vessel solution meticulously engineered to meet the extreme demands of copper melting, alloying, holding, and refining processes. Unlike standard refractories, this advanced composite crucible is specifically formulated to overcome the unique challenges posed by molten copper and its alloys - including high operational temperatures (exceeding 1085°C / 1985°F), aggressive slag formation, high fluidity leading to penetration risks, and the need for precise thermal management.

• Exceptional Thermal Stability: Withstands the high temperatures (exceeding 1100°C) required for gold melting without deformation or cracking, even under rapid thermal cycling.
• Superior Oxidation Resistance: Highly resistant to oxidation in air at elevated temperatures, protecting the crucible integrity and minimizing contamination of the precious metal melt.
• Superior Resistance to Metal Penetration: The dense, low-porosity microstructure achieved through advanced manufacturing significantly impedes the infiltration of highly fluid molten copper and copper alloys, a major failure mode for inferior refractories. This extends service life dramatically.
• Reduced Wetting & Easier Release: The graphite component minimizes the wetting tendency of molten copper, facilitating cleaner pours and reducing residual metal buildup inside the crucible.

They can be used for resistance furnace, induction furnace, biological particles furnace, gas furnace, coke oven, furnace oil, and gas furnace to melt gold, silver, copper, aluminum, tin, lead, zinc and other nonferrous metals, and various non-ferrous alloys.

• Copper: OFC, bronze, brass melting
• Aluminum: Alloy production, recycling
• Precious Metals: Gold, silver refining
• Specialty Processes: Vacuum melting, induction furnaces
