Ceramic Foundry Sand

Ceramic Foundry Sand is a high-alumina synthetic sand produced by fusing and spheroidizing high-purity bauxite. It features excellent refractoriness, high thermal conductivity, superior roundness, and low thermal expansion, making it ideal for advanced foundry and precision casting applications.

The product is available in three optimized grades: ZCF30, ZCF40, and ZCF60, each designed for specific particle size requirements and casting processes. Its consistent quality ensures high-quality castings with minimal defects.

Key Advantages

Excellent refractoriness (>1790 °C)
High thermal conductivity at elevated temperatures
Superior roundness with 99% roundness rate
Low thermal expansion and excellent thermal stability
Exceptional flowability for complex molds and cores

Main Applications

Precision casting for ferrous metals (steel, cast iron)
Precision casting for non-ferrous metals (aluminum, copper alloys)
Foundry sand molding and core-making
Refractory castable raw material
High-temperature furnace lining applications
Advanced ceramic shell mold systems
Complex metal casting with tight tolerances
