Aluminum oxide is the most commonly used abrasive. Best-suited for general purpose deburring and blending, it is tough, economical and fracture-resistant. Commonly used on ferrous alloys, high-tensile materials, and wood.
Vitrified bonds are made from a mixture of clays fused at high temperatures, creating a glass bond.
