Black Fused Aluminum Oxide

1. Description:

Black Fused Aluminum Oxide is made from high quality bauxite, iron oxide and micro-elements by melting in a tilting arc furnace. Black Fused Aluminum Oxide can be produced in a variety of sizes from grains to micro-powders. Black Fused Aluminum Oxide is also known as low aluminum corundum. Al2O3 content is 70% ~ 85%, It is also a new type product of polishing material and one of the most economical media available for a wide array of dry and wet processing applications.
