Black aluminum oxide fine grits for Brake Pads and Polishing wax
Black aluminum oxide is obtained from the fusion of high iron bauxite or high alumina bauxite in electric arc furnace. Its main component is α-Al2O3, with Al2O3 62%. With moderate hardness, Lower hardness than Brown aluminum oxide, strong tenacity, low grinding heat and less prone to surface burning, is an excellent alternative abrasive.
There are crude grits F12#-F60#, Fine grits F70#-240#, Micro powder 280#-1000#
The fine grits and micro powder is applicable to produce Brake Pads and Polishing wax.
