However, the challenge of designing such materials has remained elusive due to the temperature-dependent electron-phonon scattering. Moreover, resistive electrical conductors used in flexible and mobile systems under high mechanical loads must possess both high strength and ductility. Achieving such multi-properties presents a fundamental challenge. Here, we solve this problem by combining multicomponent alloy design with atomic-scale chemistry tuning. We term the resultant material 'Resinvar' alloy, due to its invariable resistivity (148 μΩ·cm) over wide temperature ranges from room temperature to 723 K. The alloy also has high tensile sNature communicationsStrong and ductile Resinvar alloys with temperature- and time-independent resistivity.PMC1133944751971248Raabe DLi ZHan LZhang YYan DZhu SfalseStrong and ductile Resinvar alloys with temperature- and time-independent resistivity.Materials with well-defined electrical resistivity that does not change with temperature or time are important in robotics, communication and automation.
