AC6781 Alumina Zirconia Grain, Al2O3 ZrO2 Grain

Aluminium Oxide Zirconium Dioxide Grain Description

Aluminium Oxide Zirconium Dioxide Grain is one of the hardest abrasives available. By melting zircon sand and alumina at temperatures of 1950°C, grains with high hardness and extreme toughness are produced. The zirconium dioxide grains with 40% aluminium oxide exhibit a fine crystalline structure composed of primary corundum and aluminium oxide-zirconium dioxide eutectic, providing excellent wear resistance and durability. This characteristic makes it an ideal choice for grinding applications, surpassing conventional abrasives such as brown fused alumina and silicon carbide.

Aluminium Oxide Zirconium Dioxide Grain represents a premium quality of aluminium oxide zirconium dioxide grain designed for high-pressure grinding applications such as steel conditioning, foundry, and snagging. It is characterised by outstanding wear and abrasion resistance, making it well-suited for use in steel conditioning discs, large diameter cutting discs, and other grinding processes that require high speeds and significant pressure.
