40.6% Fused Zirconia Alumina Abrasive Grain 1620kg/Mm2 Knoop Hardness
High Temperature Abrasives Material Zirconum Fused Alumina ZA25 & ZA40 for Coated Abarsives
Fused Zirconia abrasive grain is produced by putting rich aluminum, zirconium materials and additives in electric furnaces, smelting with high temperature above 2000°C, cooling down with special technology, and compacting with Barmac plastic, which has the characteristics of excellent self-sharpening ability, tenacious texture, dense structure and high strength.
