Aluminum Oxide (brown)
As an angular,
durable blasting abrasive, aluminum oxide (or aluminium oxide) can be
recycled many times. It is the most widely used abrasive grain in sand
blast finishing and surface preparation because of its cost, longevity
and hardness. Harder than other commonly used blasting materials,
aluminum oxide grit powder penetrates and cuts even the hardest metals
and sintered carbide.
Approximately 50% lighter than metallic
media, aluminum oxide abrasive grain 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.
Aluminum
oxide grit powder has a wide variety of applications, from cleaning
engine heads, valves, pistons and turbine blades in the aircraft
industry to lettering in monument and marker inscriptions. It is also
commonly used for matte finishing, as well as cleaning and preparing
parts for metalizing, plating and welding. Aluminum oxide abrasive grain
is the best choice for an abrasive sand blasting and polishing grain as
well as for preparing a surface for painting.
