Black fused alumina for resin sand wheel making
Description
Black fused alumina also known as black corundum, kind of gray-black crystal with α-Al2O3 and iron spinel as the main ore phase produced by melting aluminum bauxite in an electric arc furnace, it has the characteristics of moderate hardness, high toughness, high temperature resistance and stable thermal performance. Black fused alumina are always used for sand wheel making.
