Abstract

This invention discloses an allotype copper and aluminum wire, which comprises aluminum core and copper cover layer with non-round section. The process method comprises the following steps: processing round copper coil and aluminum compound wire; using twenty to one hundred tons of pressure to roll the wires with speed as 100-800m / min; shaping by mode pulling; match fire processing with temperature of 260-350 Deg. C.

Description

Technical field: [0001] The invention relates to a composite wire and a production method, in particular to a special-shaped (non-circular) copper-clad aluminum wire and a production method. Background technique: [0002] At present, people have developed a variety of composite wires to solve the problems of the preciousness of copper wires, the poor conductivity of aluminum wires and the increasingly scarce copper resources, such as copper-clad steel, copper-clad aluminum and other composite wires. The production method is basically the method disclosed in the Chinese invention patent application number 98112410.0 and the name is "a copper-aluminum composite wire and its production process", that is, "the fully annealed copper strip (or copper tube) is fully annealed with a metal wire wheel. After removing the passivation layer on the surface of the aluminum rod and the aluminum rod, the aluminum rod is wrapped into the copper tape by the cladding method, and the copper tape is ...
