95% Al2O3 Aluminum Oxide Grit Blasting , Sandblasting Aluminum Oxide Blast Media
High Hardness 95% Al2O3 Aluminum Oxide Brown Fused Alumina F24 F30 for Sandbalsting
1. Product Description of Aluminum Oxide Brown Fused Alumina
Brown aluminum oxide is also called as brown fused alumina,it is produced by bauxite,coke,iron scrap as the
main raw material,fused in an electric arc furnace under high temperature over 2000 degrees.
The top grade brown aluminum oxide contains 95% alumina,it has high Mohs hardness of 9,which is used in
rough grinding of ordinary steel, such as carbon steel, oridiary alloy steel, calcinable cast iron, hard bronze, etc.
It is also one popular blasting media in various applications.
