Abstract

Method for fabrication of a gold alloy wire:

an alloy is prepared including from 33.33% to 45.83% Au, from 3.64% to 12.44% Zn, from 18.46% to 45.02% Cu, from 9.88% to 33.78% Ni, and from 0.0 to 5.0% of elements from among Ir, In, Ti, Si, Ga, Re,a continuous cast bar is produced, having a diameter of 8.0 to 20.0 mm,this bar is wire rolled while limiting the cross-section deformation to less than 20% per pass, preferably 13%,the cumulative deformation compared to the initial cross-section is measured,the wire rolling is stopped when the cumulative deformation reaches 60% to 75%, an anneal is performed,the wire rolling is started again and the wire rolling, measuring, annealing process is repeated until the desired cross-section is achieved,the intermediate product is drawn to obtain a section wire of circular cross-section.
