Abstract
The invention discloses a low-resistance copper alloy wire which comprises, by mass, 1-2% of Ag, 0.5-1% of Mo, 3-5% of Ni, 0.2-0.5% of V, 1-2% of Ru, 0.2-0.5% of Zr and the balance Cu. In the melting process, Ag and Mo are added into molten copper first, and then N, V, Ru and Zr are added for mixed melting after mixing. The wire is small in resistance and high in conductivity, is applied to the power transmission process, can effectively improve transmission efficiency, and reduces losses of power resources in the transmission process as much as possible.
Description
Technical field
The present invention relates to a kind of alloy lead wire, be specifically related to a kind of low-resistance copper alloy wire.
Background technology
In power industry, the transmission of wire has very large impact to power industry.The material of wire and structure determine resistance sizes and the specific conductivity of wire.Larger resistance and lower specific conductivity limit the application of wire in power industry.Resistance is excessive, has larger loss, waste the energy to a certain extent in power transmission.
The classification of wire is more, has copper wires, aluminum wire etc.Wherein, the copper wires used in present cable, mainly annealed copper wire or it is coated with the twisting thread of the stranded formation of copper cash of tin etc.The requirement of the recent snappiness to copper wires, ductility and conductivity is also more and more higher, and existing copper wires cannot meet these requirements.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of low-resistance copper alloy wire is provided.This copper alloy wire resistance is little, is applied in power transmission process, effectively can improve the efficiency of transmission, reduces the loss of electric power resource in transmitting procedure and the physicochemical property such as erosion resistance, ductility, plasticity-of raising copper alloy wire as much as possible.
To achieve these goals, present invention employs following technical scheme:
A kind of low-resistance copper alloy wire, contain by mass percentage: 1 ~ 2%Ag, 0.5 ~ 1%Mo, 3 ~ 5%Ni, 0.2 ~ 0.5%V, 1 ~ 2%Ru, 0.2 ~ 0.5%Zr, surplus is Cu.
As technical solution of the present invention further preferably, described low-resistance copper alloy wire contains by mass percentage: 1.5%Ag, 0.8%Mo, 4%Ni, 0.4%V, 1.5%Ru, 0.3%Zr, and surplus is Cu.
The preparation technology of copper alloy wire of the present invention adopts conventional copper alloy wire production technique substantially, difference place is only: described low-resistance copper alloy wire is in fusion process, first Ag, Mo are added in copper liquid, after mixing, then add Ni, V, Ru, Zr and carry out mixed smelting.
Advantage of the present invention:
1. copper alloy wire of the present invention after measured, and its resistivity is 0.0005 Ω mm
2/ m ~ 0.0015 Ω mm
2/ m, can be widely used in power transmission, effectively reduces the loss of electric power resource.
2. copper alloy wire of the present invention is by adding and controlling the content of the metallic elements such as electric conductivity excellent Ag, Mo, improves the metallurgical structure of Optimization of Copper alloy, improves the electric conductivity of copper alloy wire; Add in addition and control the content of the metallic elements such as Ni, V, Ru, Zr of fine corrosion resistance, under the prerequisite ensureing electric conductivity, improving the physicochemical property of copper alloy wire further, extend its work-ing life.
