Zirconium Alumina is an abrasive material produced by electrofusing zirconium and alumina raw materials in an electric arc furnace, and then by quenching, crushing and sieving the fused mineral into selected grain sizes. ZA40 has small crystal size and a unique microstructure, which give it excellent toughness, hardness, cutting capacity, and durability. Depending on the application, ZA40 is often far superior to brown fused alumina, silicon carbide and other traditional abrasive materials.
| ZrO2 | Al2O3 | SiO2 | Fe2O3 | TiO2 | CaO |
|---|---|---|---|---|---|
| 38-42% | 56-60% | ≤ 1.0% | ≤ 0.5% | ≤ 0.60% | ≤ 0.15% |
F8 to F220; P20 to P220
In accordance with the current FEPA / JIS / ANSI sieve standards.
ZA40 is used for both coated and bonded abrasives, including abrasive belts, abrasive cloth, sandpaper, and resin-bonded grinding wheels, for use in an array of applications such as grinding carbon steel railways, alloy steel, stainless steel, casting surfaces, and wood.
