Product Description

Black aluminum oxide for sandblasting replace Al2O3 85% BFA stable supply 

Sandblasting High Purity Aluminum Oxide , 8.0 Mohs 2000HV Grit Aluminum Oxide Abrasive 0

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.

The application of BA grit size: F12-F220#

Sandblasting, ideal choice to replace 85% Al2O3 BFA

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.

 

Comparing with Grade A Brown Aluminum oxide (Al2O3 95%), and Grade B Brown Aluminum oxide (Al2O3 85%), Black aluminum oxide is with moderate hardness, high toughness and stable performance, can replace 85 BFA easily, and has stable supply and lower price.
