Product Description
Black aluminum oxide grits 12#,16#,24#,30#,36#,46#,54#,60# for abrasives
Black aluminum oxide, also known as Black fused alumina, low-aluminum corundum, Black emery, etc. is produced by melting high iron bauxite and high alumina bauxite in an electric arc furnace, characterizing by 62-65% low Al2O3 content. There is a certain amount of Fe2O3 (about 10%), so it has the characteristics of moderate hardness, high toughness, high temperature resistance and stable thermal performance.
The crude grits 12#, 14#, 16#, 20#, 24#, 30#,36#, 46#, 54#, 60# are mostly used for bonded abrasives, free grinding and sandblasting, etc.

The application of BA grit size: 12#, 14#, 16#, 20#, 24#, 30#,36#, 46#, 54#, 60#
Applicable to produce Resin-bonded cutting disc by mixing with BFA
Adding15%-30% black aluminum oxide grits with brown fused alumina to produce resin bonded cutting discs can improve the cuttings discs work life and the incision quality. Moreover, it can reduce the production cost obviously.
Applicable for sandblasting
Black Aluminum Oxide girts can be used as blasting media to sandblast for Stainless steel, metal products, optical glass, bamboo and wood products for impurity cleaning, vessel body de-rusting cleaning, de-burring, surface decontamination, matte treatment, pre-treatment before coating, pipeline cleaning, Jean cloth sandblasting, etching art, stress relief etc.
