Brown Fused media has a low friability, so it will NOT break down and shatter on impact easily. (NOTE: White fused AO has a high friability rating and breaks down rapidly. Sinterblast Aluminum oxide is a nice balance between the two with a medium friability, and a low price point, thus often used by powder coating companies).
