Long Service Life and Reduced Replacement Costs with SiC-C Crucibles for Industrial Applications

Product Description

Our silicon carbide-graphite (SiC-C) crucibles are engineered for high-temperature stability, thermal shock resistance, and long service life in demanding industrial applications. Manufactured using isostatic pressing technology, these crucibles combine the superior heat conductivity of graphite with the mechanical strength and oxidation resistance of silicon carbide, making them ideal for metal melting, alloy production, and high-precision thermal processing.

Available in standard and custom sizes, our crucibles are designed to withstand extreme thermal cycling (up to 1600°C) while maintaining structural integrity, ensuring consistent performance in foundries, laboratories, and recycling facilities.

Key Features & Benefits

• High-Temperature Performance: Operates effectively up to 1600°C, far exceeding aluminum’s melting point (~660°C), ensuring safety margins for overheating prevention.

• Extended Lifespan: SiC reinforcement reduces wear from molten aluminum’s erosive effects, offering 2–3x longer lifespan compared to traditional clay-graphite crucibles.

• Purity Preservation: Non-reactive surface prevents aluminum contamination, crucial for aerospace, automotive, and high-purity alloy production.

• Energy Efficiency: Faster melting reduces power consumption, lowering operational costs in high-volume applications.
