FIELD: metallurgy.
SUBSTANCE: invention relates to precision copper-based alloys for production of micro- and nano-wires, thin films and coatings with negative temperature coefficient of resistance (TCR). Proposed composition contains the following substances, in wt %: manganese - 18.0-22.0; nickel - 18.0-25.0; silicon - 2.0-4.0; boron- 1.5-4.0; germanium - 2.0-5.0; gallium - 3.0-6.0, copper making the rest.
EFFECT: expanded range of operating temperatures.
