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.
