Aluminum Oxide is widely used as a tough recoverable media for quick removal of paint, rust, and scale removal. It has also been specified for pre-paint adhesion. Aluminum Oxide (AL2O3) is a man made fused alumina that is very tough; angular blocky shaped, medium density, with a hardness of 9 on the Mohs scale. This abrasive is designed for high blasting pressures up to 90 PSI. Aluminum oxide is very good for light deburring and surface prep (bonding strength) prior to painting and coating. Aluminum Oxide creates a dull matte finish.Aluminum oxide has media life of approximately10-12 times through the blast system.
Typical Aluminum Oxide Blasting Applications:
- Cleaning of investment castings
- Scale removal in steam turbines
- Surface preparation for thermal spray coatings
- Rust removal
- Hard oxide removal (titanium,zirconium, etc.)
- Mill scale removal
- Heat treat scale removal
- Glass etching or frosting
- Monument lettering
- Aircraft engine overhaul
Aluminum Oxide Abrasive
When propelled by air, aluminum oxide acts as a powerful multi-edged abrasive tool that will penetrate the work piece, while leaving an exceptional clean, etched surfaces. It is used on metal, glass, ceramic, marble, granite and other stone surfaces. Aluminum oxide is manufactured in block shapes with multiple sharp cutting edges.
