While some manufacturers use recycled grains,Bosch uses only superior virgin grains made toexact specifications. The chemical structure of the grains determines the physical properties (i.e. shape, sharpness, hardness, friability). Common grain types used include:
- Aluminum Oxide - A tough, blocky shaped grain used for cutting metals and other high tensile strength materials without excessive fracturing.
- Silicon Carbide - A very hard and very sharp abrasive suited for non-metallic materials such as concrete.
- Aluminum Zirconium - A very fine, dense crystalline grain which can be used for rugged stock removal.
- Seeded Gel - A very fine, dense crystalline grain which can be used for rugged stock removal.
