Abstract

An elongated article usually in the form of a wire having a core of beryllium copper which is completely surrounded in cross section or clad by an alloy containing a plurality of metals with gold having the greatest percentage and particularly adapted for electrical purposes. In some cases there may be a barrier between the core and the outer cladding to prevent migration between the cladding and the core.
