High Strength Gold Melting Crucible Clay Crucibles Jewelry Casting Research Laboratories

Our high-performance refractory containers are designed for extreme thermal and chemical environments, combining the exceptional properties of silicon carbide with the plasticity and cost-effectiveness of clay binders.

• Superior Thermal Performance: Maintains structural integrity under rapid temperature fluctuations (up to 1600°C+) with high thermal conductivity and excellent resistance to thermal shock.
• Chemical Inertness: Resistant to oxidation, slag corrosion, and acidic/alkaline environments, ensuring minimal contamination during molten metal handling.
• Cost-Effective Longevity: Extended service life at competitive price points reduces operational downtime and replacement costs.
• Versatility: Suitable for induction furnaces, resistance heating systems, and gas-fired kilns in both small-scale foundries and medium-volume production facilities.

1. Non-Ferrous Metal Casting: Aluminum/copper alloys for automotive parts and electrical components; precious metals refining and jewelry casting.
2. Recycling Facilities: Efficient recovery of scrap metals (zinc, lead) with minimal material loss.
3. Die-Casting Operations: High-volume production of complex geometries in zinc/aluminum die-casting systems.
4. Research Laboratories: Small-capacity crucibles (<5kg) for R&D in advanced alloy development.

Silicon Carbide (SiC): Synthetic ceramic material with ultra-high melting point (~2,700°C), superior thermal conductivity, and resistance to thermal shock and corrosion.

Clay Binder: Aluminosilicate minerals that shape and stabilize SiC particles during fabrication, enhancing workability and reducing production costs.
