Product Overview
Our Silicon Carbide (SiC) Crucibles for Copper Melting are specifically optimized to handle the demanding conditions of copper and copper alloy processing. Designed to operate at 1650°C with superior thermal shock resistance, these crucibles are the preferred choice for copper foundries, electrical component manufacturers, and high-purity copper refining facilities.
Higher Threshold: Withstands up to 1650°C – 10% higher than standard SiC crucibles – ideal for copper’s higher melting point (1085°C).
Thermal Shock Resistance: Rapid heating/cooling cycles without cracking, critical for continuous copper casting processes.
Copper-Specific Formulation: Reinforced with anti-wetting agents to resist molten copper penetration and slag adhesion.
Oxidation Barrier: Proprietary surface treatment reduces oxidation by 40% compared to conventional SiC crucibles.
Ultra-Low Porosity: ≤12% porosity minimizes copper infiltration, preserving material purity.
Uniform Heat Distribution: Ensures consistent melting for high-quality copper alloys and wires.
Copper-Industry Tailored: Available in specialized shapes (e.g., tapered for continuous casting) and sizes (1L to 1000L).
Designed for high-stakes copper processing:
Electrical Industry: Melting copper for wires, cables, and busbars.
Electronics Manufacturing: High-purity copper for PCBs and semiconductor components.
Alloy Production: Bronze, brass, and beryllium-copper alloy casting.
Recycling Facilities: Efficient recovery of scrap copper into reusable material.
