Black fused alumina
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’s an excellent alternative abrasion-proof material.

Making resin cutting discs:
30%-50% of black corundum is mixed with brown corundum to make resin cutting discs, which can improve the sharpness of the cutting discs, have a higher cut finish, less discoloration, reduce usage costs, and improve cost performance.
Polished stainless steel cutlery:
Use black corundum grain sand and fine powder to polish stainless steel tableware, which is not easy to burn the surface of stainless steel polished workpieces, and the color is uniform.
Wear-resistant and non-slip pavement and floor:
Using black corundum section sand as aggregate to lay wear-resistant and non-slip pavement, bridge deck, parking lot floor, and make wear-resistant and non-slip floor, which can fully meet actual needs and has a very high cost performance.
Making fiber wheel:
Using black corundum granular sand or fine powder, it can be made into fiber wheels for grinding and polishing various workpieces.
The use of black corundum black corundum granular sand can be used to remove impurities on the surface of various workpieces, pipe cleaning, ship hull rust removal, and sandblasting of old denim surfaces.
Production of abrasive belts and thousand impellers:
Use black corundum to compound brown corundum or simply use black corundum to make abrasive cloth, which is converted into abrasive belts, thousand impellers, etc., for polishing various workpieces.
The use of black corundum powder can be made into various specifications of polishing wax for fine polishing of various workpieces.
