Blast media is the grit or “sand” used with abrasive blasting systems that are sometimes referred to as sandblasting tools. In these systems, blasting media is blown through a nozzle via compressed air. Different surfaces require different types of blast media for optimal cleaning, polishing, and finishing.
Blast media are used for:
- Cleaning
- Deburring
- Polishing
- Priming before painting
- Smoothing
- Shaping
- Removal of corrosion
- Removal of rust
- Removal of paint
For abrasive blasting applications, blast media are designed to be used with a variety of sandblasters and blast cabinets.
Blast Media Types
Aluminum Oxide
What is it? A common blasting media, aluminum oxide has a sharp texture and can be recycled multiple times.
What is it used for? Stripping and polishing surfaces of hard constructed metals, due to its sharp consistency.
Grit range? Extra coarse to super fine
Silicon Carbide
What is it? Silicon carbide has a blocky grain texture and represents the hardest media available. Characteristically, it does not produce static electricity.
What is it used for? Ideal for shorter blasting times. It is suited to the fast cutting speeds required for glass and stone materials.
Grit range? Extra coarse to very fine
Glass Bead
What is it? Glass bead is a type of soda blasting material comprised of lead-free soda lime glass. It can be recycled many times.
What is it used for? Generating a smooth finish, more so than the harder abrasives. Commonly used within blast cabinets.
Grit range? Extra coarse to very fine
Corn Cob
What is it? Corn cob blasting media is biodegradable media made from corn cob and wood ring.
What is it used for? For use with delicate parts, it can remove debris and surface coating on glass and metals.
Grit range? Extra coarse
