ABSTRACT:
The present invention relates to a process for forming a composite strip material without any sintering step. The process includes blending a powdered high conductivity material such as powdered copper with a powdered low thermal expansion phase material such as a nickel-iron alloy, compacting the powders to form a green composite strip, heating the green strip to a hot rolling temperature and hot rolling the heated strip to a desired gauge. The heated strip is reduced less than about 45% to minimize the deformation of the low thermal expansion phase particles.
