Product Overview

  • Brown Fused Alumina (BFA), is also known as Brown Fused Alumina or BFA, is made of superior calcined bauxite, melting at super high temperature condition approximately 2000℃ through an electric arc furnace processing.
  • Brown Fused Aluminum Oxide has a high bulk density and high hardness making it the perfect media for removing rust, mill scale, and surface contamination. The consistent particle size allows for a uniform surface finish and coverage.
