Brown Fused Alumina Refractory Grades is a mineral with fine particle distribution for shaped and unshaped refractory products in fire-proof, precision casting, foundry and coating industries. Our Brown Fused Alumina Refractory Grades is a high grade refractory material with high purity, high cleaness, coarse grain, low magnetic contents, high density, high bulk density, chemical stability, low prosity rate, nice crystal struction, corrosion and acid resistant. No cracks, corrosion or spot during production of refractory products. Brown Fused Alumina is the most popular refractory material, especially for refractory bricks.
Brown Fused Aluminium Oxide(Brown Fused Alumina) FEPA P Sizes P8-P2000 is made of FEPA/JIS standard with qualified sieve into standard coarse particle distribution. It's widely used in production of Aluminum Oxide Sand Paper, Sand Cloth, Sanding Belts etc. Our Brown Fused Aluminium Oxide is pure, sharp-edged, low in magnetic content and clean. It's an ideal synthetic corundum for coated abrasive tools.
Brown Fused Aluminium Oxide for coated abrasives is usually Roller Milled material because it has sharp edge for removing dust,rust,oxide layer,paint on surface of metal and non-metal.
