Materials

Mubea belleville disc springs are manufactured to meet the most demanding fatigue life requirements while exhibiting a minimum amount of relaxation. The choice of disc spring material directly influences these properties. For standard applications, the spring material 51 CrV 4 is used. Furthermore, special materials can be used for applications requiring:

• High corrosion resistance

• Operation at low/high temperature

• Antimagnetic properties.
