Description

Black aluminum oxide for bonded abrasives cutting disc mixing with BFA

Grit Black Oxide Aluminum 

Black aluminum oxide, also known as low-aluminum corundum, is a black gray crystal with α-Al2O3 and iron spinel as the main ore phase, produced by melting aluminum bauxite in an electric arc furnace, which is characterized by 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.

It is mostly used for free grinding, sandblasting, and polishing. Such as grinding and rough grinding before electroplating of products, sand blasting of stainless steel, metal products, optical glass, bamboo and wood products, and is also a novel abrasive for manufacturing resin grinding wheels, cutting discs and abrasive cloths.

The application of BA grit size: F12-F220#, especially 20#, 24#, 30#, 36#, 46#

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.
