Description

1.Introduction:
Brown fused alumina is fused and crystallized under high temperature of about ***0 from mixture of bauxite and other materials. Characterized by its high hardness, good toughness and shape in particles. Brown Fused Alumina is suitable for abrasive &sandblasting abrasive, refractory materials, abrasion resistance ground and also fro production mold of precision casting.
