Characteristics of Press-soldered Joints of Copper with Dissimilar Materials

Abstract

Copper and some other materials were joined using the resistance heating apparatus by which heating and pressure could be applied simultaneously. The materials used were presoldered and the alloyed layer was formed on each of them by using Pb-Sn solder.
Tensile test at the room temperature revealed that fracture of all specimens originated in copper material.
The layers consisted mainly of Cu-Sn, Cu-Zn-Sn, Cu-Ni-Sn, Cu-Fe-Ni-Sn when copper, brass, nickel, and Fe-42Ni alloys were jointed with copper respectively.
