Black Aluminum Oxide F24# F30# F36# P60# P120# for Bonded Abrasives,Coated Abrasives
1. Product Description of Black Aluminum Oxide
Black aluminum oxide is also called as black fused alumina,it select the high-alumina or high iron bauxite
as main raw material,then fused in arc furnace,finally made into different size through a series steps of cooling,crushing,screening,inspecting,packing etc.
Black aluminum oxide contains 60% min Al2O3,it has medium hardness and better self-sharpness compared
with brown aluminum oxide,it is especially suitable for polishing of stainless steel tablewares.
In addition,it also has more competitive price/performance ratio,it is also widely used for making resin cutting
discs,coated abrasives mixed with brown aluminum oxide.
Black aluminum oxide will reduce the finall production cost and also improve the products’ performance.
So It is one economical abrasive.
