Copper-clad aluminum composite guide wire high in yield strength

Abstract

The invention provides a copper-clad aluminum composite guide wire high in yield strength. The guide wire comprises a wire body, the wire body comprises a plurality of copper-clad aluminum conductor wire core sets and an aluminum copper guide wire core, the center of the aluminum copper guide wire core is an aluminum conductor, and the external layer of the aluminum conductor is a copper conductor. A tin coating is covered on an external layer of the aluminum copper guide wire core, the tin coating is combined to an outer surface of the aluminum copper guide wire core through metal composite technology, the aluminum copper guide wire core and the wire body are arranged coaxially, copper aluminum guide wire core sets are peripherally and uniformly distributed along the aluminum copper guide wire core, a cooling channel soft copper pipe is arranged in each copper aluminum guide wire core set, and the cooling channel soft copper pipe is a soft copper pipe with an insulating film taped covering and a length same with the copper-clad aluminum conductor wire core sets. A technical scheme provides a method for improving the yield strength of the copper-clad aluminum composite guide wire, and the method includes following processes:hot-rolling forming->cooling->extruding->cold rolling->stretching->annealing->stretching.

Description

[0001] technical field [0002] The invention relates to a metal wire, in particular to a copper clad aluminum composite wire with high yield strength. Background technique [0003] At present, the wires used in the market are generally pure copper wires. This is not only because the high copper price makes enterprises face rising cost pressures, but also because only the surface of the wire actually plays a role in the current transmission, and the conductivity of the material inside the wire Good or bad is insignificant, so using pure copper as a wire is actually a waste, so the market urgently needs a more economical and better wire material. Contents of the invention [0004] Aiming at the above-mentioned problems in the prior art, the present invention provides a copper-clad aluminum composite wire with high yield strength. [0005] In order to achieve the above object, the technical solution adopted by the present invention is: a copper-clad aluminum composite wire ...
