ALUMINUM OXIDE: Standard professional sandblasting media for good durability, Aluminum oxide (Al₂O₃) blast media is a synthetic abrasive made from fused alumina, derived from bauxite ore and processed at high temperatures to produce hard, angular grains. It is known for its Mohs hardness of 9, making it one of the hardest abrasives available, second only to diamond and zirconia. The angular shape of the particles allows for aggressive cutting action, efficient material removal, and precise surface profiling. It is chemically stable, non-toxic, and suitable for both dry and wet blasting applications.
