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.
