ABSTRACT:
The invention relates to the use of a copper-titanium-cobalt-alloy which consists of 0.05-0.6% titanium; 0.05-0.6% cobalt; remainder copper, whereby the cobalt is partially replaced by iron. Due to its excellent characteristics with respect to electrical and thermal conductivity, mechanical strength, softening resistance and homogeneity, the alloy is used as the material for electronic components, in particular lead frames for transistors, integrated circuits or the like, and parts for electronic components for automobiles.
