Brown fused alumina, Brown Fused Alumina (BFA) is made from Calcined Bauxite. It is a hard and tough material, used in manufacturing of grinding wheels (both vitrified and resin bonded) and coated products. These grains are also used for shot blasting and as polishing media. It is available in grit sizes as per FEPA for abrasive applications and group grits for refractory applications.
Brown Fused Alumina abrasives are mainly used for decontamination, derusting, anticorrosion, descaling, polishing and effect pattern of various materials.
Generally speaking, there are three factors that affect the effect of sandblasting:
1. Grinding force: the higher the grinding force, the better the sand blasting effect.
2. Packing density: the higher the packing density, the better the sandblasting effect.
3. Dust: the lower the dust, the better the sand blasting effect.
Brown Fused Alumina dry cleaning sand with high packing density has a very good sandblasting effect.
