Aluminium Oxide
In the family of Abrasive Blasting materials is Aluminium Oxide blasting media. Manufactured from bauxite ore.
The fused bauxite is crushed, screened, washed, tempered, baked or roasted to improve its hardness to make the final product.
Available in a number of grit sizing make it a very versatile blasting medium. The brown Aluminium Oxide is the most frequently used, but we also stock white in some grit sizes.
Aluminium Oxide blasting grains may be used wet or dry on: wood, metal, glass, ceramics, plastics, rubber, stone and other materials to remove: scale, rust, paint and burrs; to clean, cut, polish and etch surfaces.
Principal industrial applications are in the aerospace, automotive, shipbuilding, metalworking, masonry, glass and stone industries.
Aluminium Oxide grains are also used in non-slip applications on runways, flight decks, and stair treads, walkways, parking ramps and boat launching ramps.
