Glass beads are spheres of uniform size and hardness formulated of chemically inert soda-lime glass. The impact of the beads removes foreign substances from the base surface without contamination and dimensional change. Applications range from cleaning, cosmetic, deburring and light peening. It is one of the most versatile blast finishing materials available.
Excellent for cleaning where metal removal is a concern. Develops Pleasing decorative finishes.

Aluminum Oxide has a blocky shape with multiple, sharp cutting edges that penetrate work pieces, dig-out microchips and leave exceptionally clean etched surfaces. It is effective on metals, glass, ceramic, marble, granite and other stone. It has a MOHS hardness of 9 which makes it a very tough and durable material. During blasting it fractures and thereby does not create a dusty atmosphere. It is an excellent material for cleaning and providing a uniform surface or anchor pattern.
U.S. Technology Corp. pioneered dry plastic media blasting by removing paint from aircraft bodies. The MOHS hardness of the materials range between 3.0-4.0 which gives the ability to remove coatings without affecting the substrate. Over the years they have expanded the process to coating-removal requirements in the electronics, ships, vehicles, bridges and buildings. There isn't a material available that quite accomplishes what plastic media does.
Commonly known as corn cob grit, it has characteristics similar to plastic media; however, it's a lot softer. The MOHS hardness of cob is 1.0. It can be effective in cleaning fragile material but isn't as effective at removing paint and coatings as plastic media. It can also be used for light deburring and it's cost is low compared to plastic media.
Steel Grit/Steel Shot is commonly used in airless applications since it is softer than aluminum oxide and doesn't fracture as easily. It is also used in direct pressure applications where a heavy profile is needed. Steel shot is used for shot peening of ferrous materials.
Metalic abrasives are ideal for airless blasting and shot peening and they have a long life.
