White fused alumina is made from high quality Bayer-processed alumina by fusing in an electric arc furnace at high temperature. It has high hardness and better cutting characteristics. It is suitable for manufacturing of vitrified and resinoid tools, and for lapping, polishing. It can be also used to make engineering ceramic and superior refractory products.

because of ist extreme abrasive properties, ideal for descaling, derusting, stripping,roughening, dulling.
