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 materials provides high toughness but also excellent self sharpening properties. With 40% zirconia, this product promises lasting durability for coated and bonded abrasives.

AZ40-F grade products are specifically engineered for bonded abrasives. From rough, organic-bonded abrasives to precise, vitrified-bonded abrasives, JYS offers a wide range of products that can be customize to suit various needs. AZ40-F Grade products vow to increase material removal rates and to extend usability without sacrificing beautiful finishes.

AZ40-P grade products are specifically engineered for coated abrasives. While traditional abrasives dull or break at the bonding point, JYS’s AZ40-P Grade abrasives have unique fracture properties that offer microscopic precision in performance and efficient ability in high speed cutting action. These grains do not only improve the overall cutting experience, but they also extend the usability of your sandpapers, belts, or flap discs.
