Zirconia Alumina

Sandblasting material

Zirconia alumina is a high-performance abrasive made by fusing zirconium oxide with aluminum oxide in an electric arc furnace. Known for its extreme toughness, self-sharpening action, and long service life, it is ideal for heavy-duty grinding and high-pressure applications. Its micro-fracturing grain structure continually exposes new cutting edges, delivering consistent stock removal on hard metals and alloys.

Features

Exceptional toughness for aggressive grinding and extended tool life
Self-sharpening grain structure for sustained cutting efficiency
High stock removal rate under heavy pressure
Resistant to heat buildup, reducing workpiece damage
Suitable for wet or dry grinding operations

Applications

Heavy-duty grinding of stainless steel and high-alloy steels
Foundry casting and forging cleanup
Abrasive blasting for tough coatings and metal surfaces
Coated abrasives (belts, discs) for high-pressure applications
Precision grinding in aerospace, shipbuilding, and heavy machinery industries
