Zirconia fused alumina is made of high-purity alumina and zirconium material as raw materials. After high temperature smelting at 2700℃, it is formed by special processing technology and Barmac ball milling. It has high quality, extremely hard, compact structure, and special crystals. Dendritic eutectic structure. According to the content of ZrO2, zirconia alumina can be divided into ZA25 Zirconia alumina (ZrO225%) and ZA40 Zirconia alumina(ZrO2 40%).

Zirconia fused aluminaapplications:
- Used to produce heavy-duty grinding wheels, tough grinding wheels, and high-level resin-bonded grinding wheels.
2.Used for grinding and cutting hard-to- grind materials.
- Used for high-quality cutting discs, grinding discs, polishing wheels, etc.
- Used to produce coated abrasives, such as sandpaper, abrasive belts, flexible polishing wheels, fiber disc, nylon polishing wheel etc. It can improve polishing accuracy and work efficiency.
- Used in the production of wear-resistant hammers and linings.
- Used for sandblasting, suitable for marble, super-hard steel, steel castings and other materials.
- Used for high-level refractory materials, such as castables, intrusive nozzles, sliding nozzles, etc.
