Commercial Aluminum Oxide
An angular, durable blasting abrasive, Commercial aluminum oxide (or aluminum oxide) can be recycled many times. It is the most widely used abrasive grain in sand blasting finishing and surface preparation because of its cost, longevity, and hardness. Harder than other commonly used abrasive blasting materials, aluminum oxide grit powder penetrates and cuts even the hardest metals and sintered carbide.
Commercial Aluminum oxide used as a grinding and polishing abrasive may be a cost-effective, quality, efficient media for tumbling operations that need quick edge rounding, surfacing finishing, or cleaning.
Commercial aluminum oxide contains less than 1.5% free silica and is, therefore, safer to use than sand. The grit size is consistent and cut much faster than garnet sand mesh, leaving a smoother surface. Generally, the larger the grit size, the faster the aluminum oxide will cut.

Aluminum oxide can also be formulated for use in bonding applications to create slip-free surfaces on indoor and outdoor walkways, making it a preferred choice for preventing slip-and-fall accidents in industrial settings.
