Glass Bead vs Aluminum Oxide Grit

Aluminum Parts

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'.
