40% alumina-zirconia grains have 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.
Long Life
AZ40 grains are a special alloy containing about 40Wt% zirconia produced by fusing zirconia and alumina in an electric arc furnace. our 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 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.
