FIELD: non-ferrous metallurgy.
SUBSTANCE: group of inventions includes versions of a magnetic copper alloy, a method for production thereof, as well as an article from a magnetic copper alloy. Magnetic copper alloy contains, wt %: 8–16 nickel, 5–9 tin, 5–21 manganese, copper—the rest. Alloy is obtained by casting, homogenisation during 4–22 hours at 1200–1700 °F, heating alloy for 1–3 hours at 1400–1600 °F, hot rolling till reduction of 65–70 % and annealing of alloy on solid solution for 1–3 hours at 1200–1600 °F.
EFFECT: obtaining alloys with balanced combination of magnetic and mechanical properties.
