Aluminum oxide is a sharp, abrasive cutting medium that is used for sandblasting and can be reused a number of times for grit blasting. It's harder than most commonly used dry abrasive blast media.
It can cut through the hardest metals and other surfaces. This blasting medium comes in a variety of sizes too.
White Aluminum Oxide
This blasting medium is of a 99.5% ultra-pure grade. It's increasingly being used in critical, high-performance processes such as microdermabrasion.
It's also required when contamination from other metal oxides must be kept to a minimum.
Corn cob is a biodegradable blasting medium that won't etch
or warp the blasting surface. It's ideal for blasting wooden surfaces, thin metal surfaces, and plastic surfaces.
Crushed Glass Grit
This silica-free, consumable abrasive offers aggressive surface profiling and is used to remove a variety of surface coatings.
Made from 100% recycled bottle glass, crushed glass grit produces a whiter and cleaner finish that can be related to mineral or slag abrasives.
This abrasive medium creates a softer and brighter finish than angular abrasives. Glass beads are free of silica and can be used effectively for shot blasting, peening, honing, cleaning, and light deburring. It is recyclable too.
Plastic abrasives like urea, acrylic, polyester, and melamine are available in a variety of sizes. They're ideal for auto restoration jobs as they offer a high stripping rate without damaging or warping the substrate.
Considered the softest among all blasting media, pumice offers excellent stripping properties. It can be used to blast soft wooden surfaces to remove the paint or the coating without any impact on the substrate.
Silicon Carbide Grit
Silicon carbide is the hardest blasting medium that's available today. It has a fast cutting speed and can be recycled or reused more often than sand or aluminum oxide. Its hardness property allows shorter blast times.
In addition, silicon carbide grit is a more cost-effective option when compared to other blasting media.
It's an angular carbon-steel blasting medium that's designed for quick and effective removal of metal surface contaminants. It's softer than aluminum oxide and is less likely to fracture.
Blasting done with steel grit leaves an etched surface that's perfect for adhesion of paints and coatings.
This blasting medium is ideal for peening
applications as it imparts a clean, smooth, and polished finish. This dense, smooth shot can be used up to 3000 times, producing minimal dust during the blasting process.
It also helps increase the compressive strength of the metal surface.
Walnut shell grit is the most versatile organic blasting medium
due to its angular and durable shape. It's used as an economical and biodegradable alternative for sensitive blasting operations that require aggressive stripping.
