A popular tough recoverable material for rapid removal of paint, rust, and scale is aluminum oxide. Additionally, pre-paint adhesion has been specified for it. Aluminum Oxide (AL2O3), a synthetic form of fused alumina, has a hardness of 9 on the Mohs scale, is angular in shape, and is medium in density. High blasting pressures of up to 90 PSI are supported by this abrasive's design. Prior to painting and coating, aluminum oxide works well for light deburring and surface preparation (bonding strength). Aluminum oxide produces a matte surface that is drab. Through the blast system, aluminum oxide has a media life of approximately 10–12 times.
Applications of Aluminum Oxide Blasting:
- Investment castings' cleaning
- removing scale from steam turbines
- preparing the surface for thermal spray coatings
- removing rust
- removing hard oxide (titanium, zirconium, etc.)
- removal of mill scale
- removing scale with heat
- Frosting or glass etching
- Monumental signage
- overhauling an aircraft engine
Aluminum Oxide for Sale in India
Aluminum oxide is a powerful multi-edged abrasive that can penetrate the workpiece and leave behind exceptionally clean, etched surfaces when driven by air. It is applied on surfaces made of stone, including marble, granite, glass, and metal. Block-shaped aluminum oxide with several sharp cutting edges is produced.
