brasive Material White Fused Alumina Grit
Description
White fused alumina is a 99.5% ultra pure grade of blasting media. White aluminum oxide is increasingly being used in critical, high-performance microdermabrasion equipment. 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 fused alumina micropower is approximately 50% lighter than metallic media, white aluminum oxide has twice as many particles per pound. The fast-cutting action minimizes damage to thin materials by eliminating surface stresses caused by heavier, slower-cutting media blasting grits.
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.
