BrownAluminum oxide (or aluminium oxide) is an extremely sharp, long-lasting blasting abrasive that can be recycled many times. It is 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.
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 metallizing, plating and welding.
In addition to using aluminum oxide powder for sandblasting and polishing, it is also used as a durable and efficient non-skid media. The angular shape of aluminum oxide makes it an ideal grit for use in a variety of non-skid applications including concrete floors, stairs and boat decks. The inert nature of aluminum oxide allows it to be used with a variety of coating materials. The hardness of the grit particle creates a durable .long-lasting surface that requires minimal maintenance.
