Prodcut Name:Black Fused Alumina

Product Description

Black fused alumina is also known as low aluminum corundum, which is melted in electric arc furnaces by adopting the bauxite as its raw material. It has characteristics of moderate hardness, high toughness, high temperature resistance, and stable thermal stability. Black fused alumina is suitable for lapping, polishing and sandblasting of stainless steel and fabricated metal products. Further, it's used to make anti-slip material.
