FIELD: non-ferrous metallurgy, namely production of wire from tin-zinc bronze designed for making elastic members in important electric connectors.
SUBSTANCE: method comprises steps of forming blank by hot deformation; multiple drawing of blank till desired dimension of wire; before each at least three last drawing passes realizing low-temperature annealing at temperature 230±10°C and at soaking for 45 - 60 min; performing each of three last multiple drawing passes at elongation factors in range 1.25 - 1.45.
EFFECT: possibility for achieving optimal combination of strength and plastic characteristics.
