Zirconia Alumina 25

Posted on by

Description:

KZA25 is a kind of fused Zirconia Alumina abrasive with very blocky shape and tough edge. Due to the crystal is very small, this kind of abrasive grain always presents the highest toughness and very strong impact resistance.

Applications:

KZA25 is widely used in production of the overload big hot pressed steel condition wheels.
