BROWN ALUMINIUM OXIDE

Virgin, brown Aluminum Oxide Grit. >95% purity. As an angular, durable blasting abrasive, aluminum oxide (or aluminium 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 powder penetrates and cuts even the hardest metals and sintered carbide.

Aluminum oxide used as a grinding and polishing media is a cost effective and efficient media for tumbling operations that require quick edge rounding, surfacing finishing or cleaning.

Approximately 50% lighter than metallic media, aluminum oxide abrasive 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.

SPECIFICATION GUIDE

As a premier aluminum oxide abrasive grain supplier, Crystal abrasive recommends using virgin, brown aluminum oxide for optimal performance versus reprocessed or remanufactured product. Virgin, brown aluminum oxide 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 aluminum oxide will cut.
