Zirconia fused alumina is made of high-purity alumina and fused zirconia as raw materials. It is smelted at a high temperature of 2250 ° C and formed by special processing technology and Barmac ball milling. It is of high quality, extremely hard, compact in structure and special crystal. Branched eutectic structure. Zirconium fused alumina can be divided into ZA25 zirconia fused alumina (ZrO2 25%) and ZA40 zirconia fused alumina (ZrO2 40%) according to the content of ZrO2.

ZA25
Zirconia fused alumina (ZA25) is widely used for steel conditioning wheels, snagging wheels, large diameter cutting-offs, and other grinding application which requires high speed and pressure.
ZA40
Zirconia fused alumina (ZA40) is mainly used for Resin bonded abrasive and coated abrasive such as heavy duty belts, flap discs and sand discs, and show outstanding performance.
