Prodcut Name:Zirconia Fused Alumina (ZA)

Product Description

Zirconia alumina is a mixture of zirconium dioxide and aluminum oxide, which involves the fusion of Zirconia and Alumina at temperature of 2000 centi degree. It is commonly used as a sand-blasting medium and in casting and foundry applications. Its abrasive qualities make it an excellent candidate for the manufacture of grinding wheels and discs.

H-ZA25 is a kind of high quality abrasive grain with the characteristic of high intensity, extreme toughness and high temperature resisting. The most common applications are in high pressure grinding wheels and pressure blasting of very hard surfaces.
