Product Description
Description:
ZA25 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:
ZA25 is widely used in production of the overload big hot pressed steel condition wheels.
