30-60 Mesh High-purity Cast Mullite Sand is a specialized refractory material designed for high-precision investment casting and foundry shell construction. Featuring a robust 55-65% Mullite Phase and a consistent 46% Al2O3 Content, this sand provides superior thermal shock resistance and low thermal expansion. The 30-60 mesh size is specifically graded to ensure a smooth surface finish on casts while maintaining excellent gas permeability for the molding process.
Engineered for extreme environments, this product boasts a High Refractoriness (1770-2000°C), making it the ideal choice for casting stainless steel, alloy steels, and other high-temperature metals. Its high-purity composition reduces the risk of mold-metal reactions, ensuring clean, intricate casts with minimal defects. Whether used in aerospace, automotive, or industrial machinery production, our mullite sand delivers the structural stability required for complex geometries.
Our 30-60 Mesh High-purity Cast Mullite Sand is conveniently packaged in a durable 25kg/bag format, making it easy to handle, store, and transport for both small-scale foundries and large industrial plants. Produced under strict quality control, this refractory sand offers consistent particle distribution and exceptional durability. Secure your bulk supply today and benefit from a high-performance casting medium that optimizes your production yield.
