Abstract
The invention relates to a copper-chromium-titanium-silicon alloy which consists of 0.1 to 0.5% chromium, 0.05 to 0.5% titanium and 0.01 to 0.1% silicon, the remainder comprising copper and usual impurities. Because of its excellent properties as regards electrical and thermal conductivity, mechanical strength, resistance to softening, homogeneity and flexibility, the alloy is employed as a material for electronic components, in particular semiconductor carriers for transistors, integrated circuits or the like, and parts for electrical systems for cars.
