Abstract
A process for producing a Cu-Fe-Co-Ti alloy useful as conductor elements in the electronics and connector industries. The alloy is produced in the form of a bath having a Ti/Fe+Co ratio between 0.3 and 1 and a Co/Fe ratio between 0.10 and 0.90. The molten alloy bath is deoxidized with boron, cast, homogenized, cold drawn, and subjected to a precipitation heat treatment at a temperature lower, by at most 80.degree. C., than a temperature TM leading to the maximum electric conductivity.
