Grit Material Type

Each grit material has different attributes, such as brittleness and hardness. When choosing a grit material, take into account the qualities associated with that grit material for the intended application. In some cases, two grit materials are blended to offer qualities intermediate to those materials alone. For example, aluminum oxide is durable, but silicon carbide is aggressive. A blend of silicon carbide and aluminum oxide would be more durable than silicon carbide alone, and more aggressive than aluminum oxide alone.

  • Aluminum oxide is a widely used and versatile abrasive material. It is a tough, fracture- and wear-resistant grit that works well with a broad range of materials, from metals to wood. Aluminum oxide is more durable than silicon carbide and often used for material removal and finishing.
