Application Properties for the Selection of Copper Alloys

Important for the usage as spring contact components are, besides mechanical strength and electrical conductivity, mainly the typical spring properties such as the maximum spring bending limit and the fatigue strength as well as the bendability. During severe thermal stressing the behavior of spring materials is determined by their softening and relaxation. The following briefly describes these material properties.

Spring Bending Limit

The spring bending limit is defined as the boundary condition under which a...
