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.
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).
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.
