SFARST

Brown Fused Aluminum Oxide

SFARST is a semi-friable brown fused aluminum oxide obtained by a reductive fusion of high purity bauxites in electric arc furnaces. The grits are silane coated, which promotes a better connection between the abrasive grain and phenolic resin binder. In order to improve its quality this material is heat treated at high temperatures. SFARST is recommended for high performance bonded abrasives. Produced according to ANSI or FEPA-F.
