Glass Bead (left) vs Aluminum Oxide Grit (right) |
These pictures show the differences between blasting an aluminum part (middle of top picture) with either a Glass Bead – 100/170 Medium-Fine and Aluminum Oxide Grit – 220 Mesh.
The Glass Bead blasted part has much more a peened, smooth, uniform finish. The Aluminum Oxide Grit blasted part also has a uniform finish but is more etched and ‘darker’.
