Abstract
Wires made of copper-based compositions are disclosed, in which the compositions preferably contain aluminum, tin, and silicon. Formulations containing solely tin and aluminum, and solely tin and silicon are also disclosed. By practice of the invention, substantial improvements in bond strength and quality of the surface finish are achieved, as compared with prior art wire compositions.
