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.
Coated ceramic sand is a high-performance material used in the casting industry for making molds and cores. It represents a significant upgrade over traditional silica sand, especially for producing high-integrity, complex castings.
Ceramic Foundry Sand for Vacuum Casting refers to a specialized, high-performance material used to create the rigid mold shells that house the flexible silicone molds in the vacuum casting process.

Using fused ceramic sand with furan resin molding is a high-performance strategy for foundries aiming to produce superior quality castings, particularly in steel.
