Silicon carbide grit for blasting (or aluminum oxide grit) is a sharp, durable tumbling abrasive. Aluminum oxide tumbling media is a cost effective and efficient media for tumbling operations that require quick edge rounding, surfacing finishing or cleaning. The hardness of aluminum oxide grit allows it to be recycled many times. It is the most widely used abrasive in surface preparation because of its cost, longevity and hardness. Harder and more cost effective 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 aluminum oxide grit powder for surface finishing, aluminum oxide tumbling media 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.
