AZ40 Fused Alumina Zirconia – High-Performance Abrasive Material for Industrial
Applications
Product Overview
AZ40 Fused Alumina Zirconia is a high-performance abrasive material designed for coated and bonded abrasives, offering exceptional toughness, durability, and cutting efficiency. It is produced by fusing alumina (Al₂O₃) and zirconia (ZrO₂) at temperatures above 2000°C in an electric arc furnace. The 40% zirconia content gives it unique self-sharpening properties, making it one of the most efficient and long-lasting grinding materials in the industry.
Due to its high fracture toughness, wear resistance, and thermal stability, AZ40 is widely used in heavy-duty grinding applications where high pressure and extreme temperatures are involved. It is ideal for cutting and grinding stainless steel, high-alloy steels, and aerospace alloys.
Key Features & Benefits

-
With a Knoop hardness of 1620 g/mm², AZ40 exhibits excellent resistance to abrasion and impact, making it suitable for heavy-duty grinding and polishing applications.
-
Reduces abrasive wear, extending the lifespan of coated and bonded abrasives.
2. Self-Sharpening for Superior Cutting Power
-
The unique microstructure of AZ40 promotes continuous fracture, exposing new sharp edges during grinding for enhanced cutting efficiency.
-
Reduces heat buildup and material burning, improving workpiece finish.
3. High Density & Thermal Stability
-
Absolute density of 4.65 g/cm³, allowing for more aggressive grinding action.
-
Maintains mechanical strength at high temperatures, making it suitable for high-speed cutting and extreme grinding conditions.
4. Chemical Stability & Corrosion Resistance
-
Resistant to most acids, alkalis, and oxidation, ensuring long-term performance in harsh industrial environments.
5. Versatile Applications
-
AZ40 is compatible with both bonded and coated abrasives, making it a go-to material for metal grinding, steel cutting, and surface preparation.
