Product Description

Moderate Aluminium Oxide Black Blasting Media for Polishing Stainless Steel Tableware

1. Product Description of Aluminum Oxide Black

Black Aluminum Oxide is one special artifical corundum, it selects the high iron bauxite, highalumina bauxite as main raw materials,then smelted in the electric arc furnace completely,finally made into different grit size after series of processes.


It contians at least 62% Al2O3,which is similar to the second grade brown aluminum oxide,while it is different from the 2rd grade brown aluminum oxide,since it is one kind of artifical corundum made by special process,which has stable chemical composition and crystal structure,while the 2rd brown aluminum oxide is the non qualified products of top quality of brown aluminum oxide.
