Saint-Gobain Abrasive Grains' 40% alumina-zirconia grains are the toughest on the market. By fusing zircon sand and alumina at temperatures of 1950° C, Saint-Gobain Abrasive Grains 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.

Produced by fusing zirconia and alumina, AZ25 1520 features a fine primary corundum and alumina-zirconia crystalline structure, which delivers 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. AZ25 1520 grains are 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

AZ40 1564 and AZ40 1578 grains are a special alloy containing about 40Wt% zirconia produced by fusing zirconia and alumina in an electric arc furnace. Saint-Gobain Abrasive Grains' unique process develops very small crystal sizes and unique columnar microstructures, generating high self-dressing ability. These special microstructures give the abrasive grains their hardness and toughness, resulting in long life and cutting/grinding efficiency on bonded abrasives.

AZ40 1565 and AZ40 1575 can be used for high-performance coated abrasives such as heavy-duty belts, flap discs and fiber discs. They show outstanding performance when dealing with metal that is difficult to grind. AZ40 1575 grains are treated to improve the electrostatic coating process.
