WHITE ALUMINUM OXIDE
This media is pure, clear white aluminum oxide, it is the most friable aluminum oxide. Due to its high purity large crystal size, crystals fracture comparatively swiftly, constantly exposing fresh cutting crystals to the work piece.
White Aluminum Oxide is offered in a wide range of sizes from fine to extra course. It can be recycled several times depending on whether it is used in a suction or pressure blast system.
White Aluminum Oxide can be used for blast cleaning, etching, polishing, lapping, dental polishing and many other applications.
