ABSTRACT:
A heat-responsive element has two links joined with a thin solder layer in a face-to-face relationship over an extended surface area. The components of opposed surfaces of the links in contact with the solder layer and the solder layer are adapted to alloy with each other in the regions immediately adjacent each opposed surface to form alloy bonds between the opposed surfaces and the solder layer. The strength of these bonds is greater than the strength of the solder layer. At least the opposed surfaces of the links consist, at least in part, of an alloy-forming amount of nickel, cobalt, chromium or iron, or an alloy of nickel, cobalt, chromium, or iron.
