Ceramic fused sand, also known as ceramic bead sand is a high-performance spherical synthetic foundry sand made from high-purity alumina raw materials through high-temperature fusion and spheroidization. It is widely recognized as the ideal filling and core-making material for copper tube gravity / die casting.
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.”
Chromite sand remains the “high-performance tool” in the steel foundry’s arsenal. It solves specific, severe technical problems—particularly with reactive alloys and solidification defects—that other sands cannot.
Ceramic sand, particularly spherical aluminosilicate bead sand , is the foundational material that makes industrial sand 3D printing viable and successful. Its superior flowability enables the precision layer deposition of the printing process, while its foundry performance characteristics (low expansion, high refractoriness) ensure the printed molds produce high-quality castings.
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
