Zirconia Fused Alumina Introduction
Fused Alumina Zirconia AZ40
AZ40 represents a Fused Alumina-Zirconia type of eutectic composition produced by melting alumina and Zirconia at about 2000℃ temperature in an electric arc furnace followed by cooling of the motion product. The very fine and homogenous microstructure of this material provides high toughness but also excellent self-sharpening property. With 40% zirconia, this product promises lasting durability for coated and bonded abrasives.

AZ40-F grade are specifically used for bonded abrasives. From rough, organic-bonded abrasives to precise, vitrified-bonded abrasives, we offer a wide range of products that can be customized for various applications. AZ40-F grade can be used to increase removal rate of material and to extend usability without influence for the beautiful finishes.

AZ40-P grade are specifically used for coated abrasives. While the traditional grains are dull or broken at the bonding point, AZ40-P grade grains is characterized with unique fracture to offer microscopic precision in performance and efficient ability during high speed cutting. These grains not only improve the overall cutting, but also extend the usability of the sandpapers, belts or flap discs.
