Ceramic Fused Alumina (CFA) for Lost Foam Casting is a premium, high-performance molding aggregate, often referred to by its common trade names like “Cerabeads” or “Spherical Ceramic Sand.”

Ceramic fused sand is a superior alternative to silica sand, especially for high-precision, high-temperature casting applications. Its durability, thermal stability, and reusability make it cost-effective in the long run, while its environmental and safety benefits add further value.

Ceramsite sand is a kind of fused ceramic sand,it is made from calcined bauxite with main content aluminium oxide processed by melting,blowing,sieving and blending.

Choosing the right size of ceramic sand for foundry applications depends on several factors, including the type of casting process, metal being poured, mold design, and surface finish requirements

the main application of Foundry Ceramic Fused Sand is as a high-performance molding aggregate in advanced and precision casting processes like Lost Foam, V-Process, 3D Sand Printing, and high-quality core making, where its superior thermal stability, spherical shape, and durability lead to higher casting quality, lower defect rates, and reduced overall production costs.

Using ceramic foundry sand as stuffing (or backing) sand is a advanced foundry practice where it forms the bulk of the mold behind a high-performance facing sand
