Main Applications
1.Making zircon fused alumina brick and building materials
2.Used for making bonded abrasives products,and process of grinding,sandblasting,surface treatment of metal products and other materials.
3.With good melt erosion resistance,Zirconia fused alumina has good grinding effect on steel,iron casting,heat resistant steel and other alloy materials.
4.Zirconia fused alumina can be made for heavy duty Zirconia fused alumina grinding wheel,snagging,cutting disc,Fiber disc,grinding rails,high speed abrasive belts etc
5.Used for making coated abrasives products,
6.Used for making lapping paste,polishing wax,emery cloth,sandpaper etc
7.Fused Alumina-Zirconia is primarily used for steel conditioning wheels, snagging wheels, large diameter cut-offs and other grinding applications that require high speed and pressure. It's also is recommended for refractories that require a high resistance to environmental corrosion and a low coefficient of thermal expansion. Applications include slide gates, glass tank refractories, and other applications requiring resistance to molten slags.
