Black fused alumina is a dark gray crystal obtained from the fusion of high iron bauxite or high alumina bauxite in electric arc furnace. Its main components are α- Al2O3 and hercynite. It features with moderate hardness, strong tenacity, good
self-sharpening, low grinding heat and less prone to surface burning, making it an excellent alternative abrasion-proof material.
