AZ 25/AZ 40
High Hardness and Extreme Toughness
Saint-Gobain’s 40% alumina-zirconia grains are the toughest on the market. By fusing zircon sand and alumina at temperatures of 1950° C, Saint-Gobain creates particles with high hardness and extreme toughness. Extremely wear resistant, the 40% alumina zirconia grains consist of fine primary corundum and alumina-zirconia eutectic crystalline structure, which allows for one of the most durable materials in the abrasives industry, outperforming commodity abrasives like brown fused aluminum oxide and silicon carbide.
AZ 25 1520 is produced by fusing zirconia and alumina at about 1950°C. This Saint-Gobain grain features a fine primary corundum and alumina-zirconia sub-eutectic crystalline structure, which provides it with extremely wear resistant and anti-friable properties. It is particularly well suited for tough grinding applications like high-pressure grinding for steel conditioning, foundry and snagging. AZ 25 1520 is primarily used for steel conditioning wheels, snagging wheels, large diameter cut-offs and other grinding applications that require high speed and pressure.
Long life and dramatic stock removal
AZ 40 1564 and AZ 40 1578 grains are a special eutectic alloy containing about 40Wt% zirconia produced by fusing zirconia and alumina at about 1900°C in an electric arc furnace. Saint-Gobain’s unique process develops very small crystal sizes and unique columnar eutectic microstructures, generating high self-dressing ability. The special microstructures provide good hardness and high toughness to abrasive grains, which demonstrate great lifetimes and cutting/grinding efficiency on bonded abrasives.

Saint-Gobain’s unique process develops very small crystal sizes and unique columnar eutectic microstructures, generating high self-dressing ability for bonded abrasive applications. The controlled fracture property combined with the sharp shape dramatically improves stock removal rate, outperforming commodity abrasive grains such as brown fused alumina and silicon carbide.
AZ 40 1565 and AZ 40 1575 can be used for high-performance coated abrasives such as heavy-duty belts, flap discs and sand discs. They show outstanding performance when dealing with metal that is difficult to grind. AZ 40 1575 is treated with coating to improve the electrostatic coating process.
