White Aluminum Oxide Grit
White Aluminum Oxide Grit is a >99% ultra-pure grade of abrasive media. It is increasingly being used in critical, high-performance processes that are sensitive to contamination and cleanliness.
White Aluminum Oxide Grit
White aluminum oxide grit is a 99.5% ultra pure grade of blasting media. The purity of this media along with the variety of grit sizes available make it ideal for both traditional microdermabrasion processes as well as high-quality exfoliating creams.
White aluminum oxide grit is an extremely sharp, long-lasting blasting abrasive that can be re-blasted many times. It is one of the most widely used abrasive in blast finishing and surface preparation because of its cost, longevity, and hardness. Harder than other commonly used blasting materials, white aluminum oxide grains penetrate and cut even the hardest metals and sintered carbide.
White aluminum oxide blasting media has a wide variety of applications, including cleaning engine heads, valves, pistons and turbine blades in the aircraft and automotive industries. White aluminum oxide is also an excellent choice for preparing a hard surface for painting.
White aluminum oxide contains less than 0.2% free silica and is therefore safer to use than sand. The grit size is consistent and cuts much faster than other sand blasting media, leaving a smoother surface.
