Product Description

        36# Sand Blasting Grit Brown Fused Alumina with Al2O3 95%

Product Description

BFA/ Brown Fused is made of high-quality bauxite, iron filings and anthracite in high temperature arc. It is crushed and shaped by self-grinding machine, magnetically removed and sieved into various particle sizes. The main chemical composition is AL2O3, which is 94.5%- -97%, additionally containing a small amount of Fe, Si, Ti, and the like. Its texture is compact, high hardness, brown, toughness, and spherical shape. It is suitable for the manufacture of ceramics, resin high-density abrasives, grinding, polishing, sandblasting, precision casting, refractory materials, etc.
