They also can be used to fill gaps between machine parts that are prone to wear. Shapes include round, notched, and slotted.

Corrosion resistance describes the material's ability to prevent deterioration caused by atmosphere, moisture, or other medium. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation.
