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.
Claims9
A supporting or connecting element of an electronic device, said element being made of an alloy consisting of:
- ______________________________________ Ti 0.05-0.6 wt. % Co 0.05-0.6 wt. % Cu and balance unavoidable impurities ______________________________________
- wherein the weight ratio of Ti/Co is from 1.0 to 1.5.
An alloy consisting of from 0.05 to 0.6 percent by weight of titanium, from 0.05 to 0.6 percent by weight of cobalt and the balance is copper and unavoidable impurities, the weight ratio of Ti/Co being from 1/1 to 1.5/1.
An alloy consisting of from 0.2 to 0.5 percent by weight of titanium, from 0.2 to 0.5 percent by weight of cobalt and the balance being copper and unavoidable impurities, the weight ratio of Ti/Co being from 1/1 to 1.5/1.
