Pressure blasting or so called sandblasting is an ideal way to cut, clean, polish, de-scale, or prepare a surface for finishing. Abrasive grains, when propelled by air through a blasting gun or hose, become powerful multi-edged abrasive tools that penetrate work pieces, dig out microchips, and leave exceptionally clean, etched surfaces in their wake. Pressure blasting can be a wet or dry process and is used on metals, glass, ceramics, marble, granite, and other stone. Pressure blasting can be used to clean very large surfaces such as rust removal on a bridge or ship or on small and precise components such as electronic parts or medical devices.

A closely sized, tough, medium density, virgin fused brown aluminum oxide abrasive. One of the hardest and toughest abrasives you can buy, Blastite is designed for the pressure blasting of materials of almost every type, including: glass, granite, marble, and ceramic and it is also used for the preparation of surfaces prior to painting or bonding; as well as for light de-burring, scale removal, and the generation of matte finishes.
A group graded, virgin brown aluminum oxide for use in blasting operations where size control is less critical.
A more closely graded, high purity fused white aluminum oxide that is composed of sharp, friable grains - specially treated for removal of iron. It is a more costly, premium material - for use where surface contamination is unacceptable.
An extremely hard, sharp grain that is more friable than aluminum oxide. Designed for or use in blasting of extremely hard materials.
