ZIRCONIA FUSED ALUMINA
Zirconia fused alumina was made from aluminum and Zirconium oxide by melting above 2250C in the electric arc furnace and cooling,then the huge zirconia fused alumina lump is crushed into different sizes.

MOSTLY USED AS :
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,it has good grinding effect on steel,iron casting,heat resistant steel and other alloy materials.
4.It can be made for heavy duty ZFA 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
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.
