Product Description
Black Fused Alumina 1-3mm Grits
Black fused alumina, also known as black aluminum oxide, is a high-performance abrasive material manufactured from premium bauxite ore through electric arc furnace fusion at elevated temperatures. This process reduces aluminum oxide content, resulting in a composition primarily consisting of aluminum oxide and iron oxide.
