FIELD: metallurgy.
SUBSTANCE: invention relates to precision copper-based alloys for producing wear-resistant nanostructured coatings with a negative temperature coefficient of electrical resistance. The alloy contains, wt.%: manganese 18.0-22.0; nickel 18.0-25.0; germanium 2.0-5.0; gallium 3.0-6.0; zirconium 5.0-8.0; titanium carbide 4.0-6.0; copper - the rest.
EFFECT: wear-resistant copper-based alloy for producing functional coatings with high wear resistance has a negative TCR, high microhardness up to 25 GPa and wear resistance up to 1.2⋅10-9 mm/km.
