Silicon Carbide Crucible for Copper Melting

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.

Key Differentiators

1. Extreme Temperature Resilience

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.

2. Enhanced Corrosion Resistance

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.

3. Precision Performance

Ultra-Low Porosity: ≤12% porosity minimizes copper infiltration, preserving material purity.

Uniform Heat Distribution: Ensures consistent melting for high-quality copper alloys and wires.

4. Customized Solutions

Copper-Industry Tailored: Available in specialized shapes (e.g., tapered for continuous casting) and sizes (1L to 1000L).

Applications

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.
