White Aluminum Oxide

White aluminum oxide (or white aluminium oxide) grit is a 99.5% ultra pure grade media. White aluminum oxide is used in applications where critical, high performance processes where cleanliness is required. This sharp, durable abrasive provide excellent edge rounding, surface finishing and cleaning. The purity of the product means that contamination from other metal oxides is significantly reduced and parts come out of the process clean and ready for further processing. White aluminum oxide is an extremely sharp, long-lasting abrasive that can be recycled many times. Harder than other commonly used abrasive tumbling media, aluminum oxide grit powder will provide efficient deburring and edge rounding on even the most difficult parts. Be sure to consider the size of perforations or holes through which the grit must pass when screen separating parts from media after use.

In addition to using white aluminum oxide grit powder for surface finishing, white aluminum oxide tumbling media is also used as a durable and efficient non-skid media. The white color minimizes the 'darkening' or 'dilution' of colored coatings. 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.
