NON-METALLIC ABRASIVES
Brown Fused Alumina (BFA)
Brown Fused Alumina (BFA) is a high-hardness abrasive produced by fusing bauxite in electric arc furnaces. Its sharp, angular grain provides excellent cutting ability, high durability, and consistent surface finish in blasting, grinding, and coating preparation.
Available in A / B / C purity grades, allowing precise selection for any industrial application — from heavy-duty blasting to fine surface finishing.
