A method for producing of highly strength electroconductive wire involves melting of biphase alloy on the basis of copper with uniformly distributed particles of the second phase plastic and alloy deformation into the wire or stripe. The alloy deformation is carried out into two stages, at that deformation on the first stage is carried out with elongation R=(0.2-0.3)D2initial/µm2 (where Dinitial – is the middle size of the particles of the second phase in the initial ingot, µm), after which the thermal treatment is carried out, which consists of annealing, which is carried out at the temperature, which is higher than the temperature of recrystallization of the second phase, but which is less than the temperature of copper melting to the recrystallization of fibers of the second phase, and subsequent annealing at the temperature, which is less than the temperature of maximum solubility of the second phase in the copper, but higher than the temperature at which the solubility amounts 25% from the maximum before the achievement of equilibrium value of solubility, and the deformation stage is carried out with the elongation of R=(0.4-0.5)D2initial/µm2.
