Abstract

A novel stretchable coaxial NiTi-sheath/Cu-core composite wire was fabricated by means of simple mechanical processing. This composite simultaneously possesses high electric conductivity, high strength and superelasticity. This set of properties renders this composite a unique position in the properties chart of all known electrical conductor materials.
