Silicon Carbide Crucible for Copper Melting

Product Overview

Specifically engineered for aluminum melting and casting, our Silicon Carbide (SiC) Crucibles deliver exceptional thermal performance and longevity. Designed to operate seamlessly at temperatures up to 1600°C (2912°F), these crucibles are the go-to choice for aluminum foundries, recycling plants, and die-casting operations seeking to enhance productivity and reduce costs.

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

Our SiC Crucibles are trusted in:

​Aluminum Foundries: For melting and casting high-quality aluminum alloys.

Metal Recycling: Efficiently processing scrap aluminum for reuse.

Die-Casting: Precision casting of aluminum components for automotive and industrial use.

Research & Development: High-temperature experiments involving aluminum and its alloys.
