99% white corundum for high speed steel cutting

Description

White corundum, also called white fused alumina. It is made by high quality alumina oxide powder, under the rocedure of melting above 2 000° in the electric furnace and then cooling. It is hard and have remarkable cutting performance, WFA is a good choice for high speed steel cutting.

Advantages of White corundum

• High hardness
• Fire resistance
• Corrosion resistance
• Wear resistance

Application of White corundum
