WEAR-RESISTANT COPPER BASED ALLOY WITH NEGATIVE TEMPERATURE COEFFICIENT OF RESISTANCE Russian patent published in 2023 - IPC C22C9/05 C22C9/06 C22C32/00

Abstract RU 2796582 C1

FIELD: alloys.

SUBSTANCE: invention is related to the field of creating resistive alloys based on copper and can be used to obtain wear-resistant coatings with a negative temperature coefficient of resistance when creating miniature sensors. The copper-based alloy contains, in % by weight: manganese 18.0-22.0, nickel 18.0-25.0, germanium 2.0-5.0, gallium 3.0-6.0, cerium 0.6-0.9, lanthanum 0, 4-0.8, yttrium 0.5-0.9, titanium diboride 6.0-9.0, and the rest is copper.

EFFECT: development of a copper-based alloy with a negative temperature coefficient of resistance and high microhardness.
