WFA high quality white fused alumina for sophimachine polishing

Description

White fused alumina are made from high quality alumina by melting above 2 000° in the electric arc furnace and cooling. It is white with main crystal phase αAl2O3. The white alumina produced in the titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved. It has great performance in polishing.

Advantages of White Fused Alumina

• High temperature resistance
• Corrosion resistance
• Wear resistance
• High hardness
• Low coefficient of expansion

Application of White Fused Alumina

• Precision machinery polishing
