Sandblasting abrasive material types
CRUSHED GLASS
Made from 100% recycled glass, this abrasive creates a sharp profile and is useful in removing a variety of coatings. It produces a whiter, cleaner finish than slags and mineral sands. Crushed glass is the abrasive of choice for preparing concrete.
Mesh sizes: 30-400 | Hardness: 5.5-7 MOHS | Density: 2.5 SG | Shape: Angular |
GLASS BEADS
Glass beads are used for general cleaning, peening and cosmetic finishing of sensitive metal surfaces; removing automotive paint; brightening grout and removing fungus and calcium deposits from tile; polishing cast iron, stainless steel, aluminium, propellers and turbine blades.
Mesh sizes: 30-325 | Hardness: 5.5-6 MOHS | Density: 2.5 SG | Shape: Rounded |
ALUMINUM OXIDE
Aluminum Oxide
Highly aggressive abrasive. Ideal for applications where tough contamination is encountered and surface removal of .0005″ to .08″ is acceptable. Resulting finish is ideal for painting, plating and coating.
Grit sizes range from #12 (coarse) to #240 (fine).
