FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy field and can be used for manufacturing of fine mechanics parts. To increase durability the alloy has the following composition, wt %: copper 53.0-57.0; manganese 3.0-4.0; aluminium 2.0-3.0; lead 0.2-0.3; phosphorus 0.02-0.03; sulphur 0.01-0.02; zirconium 0.3-0.4; vanadium 0.25-0.35; zinc - the rest. Ultimate tensile strength is approximately 700 MPa.
EFFECT: upgrading of alloy strength.
