Composite Spring Washers


Composite washers have a significant advantage over carbon steel because they are typically 70% lighter, non-corrosive, chemical resistant, and non-magnetic. Their composite material construction provides a high stregnth-to-weight ratio compared to traditional metallic construction and can be designed to provide the same functional performance as steel components.
