used as a grinding and polishing media is a cost-effective and efficient medium for tumbling operations that require quick edge rounding, surfacing finishing, or cleaning. Approximately 50% lighter than metallic media, aluminum oxide grit 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 contains less than 1.5% free silica and is, therefore, safer to use than sand. The grit size is consistent and cuts much faster than sand, leaving a smoother surface. Generally, the larger the grit size, the faster the aluminum oxide grit will cut, aluminum oxide (or aluminum 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 manufacturers penetrates and cuts even the hardest metals and sintered carbide.
