Brown Fused Alumina with High Temperature Treatment P Grains

Brown Fused Alumina with High Temperature Treatment P Grains

Brown Fused Alumina for coated abrasives is produced under well water-washing and carefully sieving again on the basis of FEPA Standard.

This is the kind of Brown Fused Aluminium Oxide grain for coated abrasives application is calcined under 1050℃-1300℃, the grain shape is very sharp, high abrasive ability , good self-sharpening and very good toughness with the high temperature treatment. It is used for producing high quality all kinds of coated abrasives products, such as sand paper, cloth, belts, and so on.
