Aluminium Oxide is an angular, durable and long-lasting blasting abrasive which can be recycled many times. It is the most widely used abrasive grain in sand blasting finishing and surface because of the its cost, longevity and hardness. Harder than other commonly used blasting materials, aluminium oxide penetrates and cuts even the hardest metals and sintered carbide.
Approximately 50% lighter than metallic media, aluminium oxide abrasive has twice as many particles per pound. The fast-cutting minimizes damage to thin materials by eliminating surface stress caused by heavier, slower cutting media.

Brown Fused Aluminum Oxide have a low friability, so it will break down slowly and coarser sizes can be recycled and reclaimed.

White Fused Aluminum Oxide have a high friability, but has the same hardness rating (in general) of Brown Aluminum Oxide. It will thus shatter on impact and break down quickly, without doing as much damage/impact to the substrate.
