Aluminum Oxide

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
