According to the copper-clad aluminum magnesium alloy for the cable, the cerium element is a rare-earth element added in the Al-Mg alloy, and can effectively improve the conductivity property of the aluminum magnesium alloy; MnCr is a compound added in the Al-Mg alloy, and can effectively improve the heat-treatment performance; and the zirconium element is a rare-earth element added in the Al-Mg alloy, and can effectively improve the plastic property and enhance the strength.
Description
Technical field
The present invention relates to the field of cable, especially a kind of cable is used copper clad aluminum magnesium alloy.
Background technology
Along with development of science and technology, the use of cable more and more widely.At present, cable is normally by the cable of several or at least two every group stranded similar ropes that form of several groups of leads, mutually insulated between every group of lead; And often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation, and the heart yearn great majority in its cable are copper wires; Owing to adopt the design of copper; Its price is expensive and density is higher, and oxidation is caused on the surface of copper for a long time easily, causes thermoplastic property difference and intensity low.
Summary of the invention
The technical problem that the present invention will solve is: in order to overcome the above-mentioned middle problem that exists, provide a kind of cable to use copper clad aluminum magnesium alloy, its thermoplastic property height and intensity are high.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cable is used copper clad aluminum magnesium alloy, by the percentage by weight of component is: Si:0.5～0.7%; Fe:0.1～0.12%; Cu:＜0.001%; Mn:0.001～0.003%; Mg:0.5～1%; Cr:0.02～0.03%; Zn:0.006～0.008%, Ce:0.001～0.002%; MnCr:0.04～0.06; Zr:0.01～0.02%, surplus are Al.
Percentage by weight by component is: Si:0.6%; Fe:0.11%; Cu:＜0.001%; Mn:0.002%; Mg:0.98%; Cr:0.023%; Zn:0.007%, Ce:0.001%; MnCr:0.06%; Zr:0.01%, surplus is Al.
The invention has the beneficial effects as follows that cable of the present invention is used copper clad aluminum magnesium alloy, owing to increased rare earth element; Can change heat treatment of alloy property, radially molecular structure, plasticity and intensity, cerium (ce) element is the rare earth element that adds in the Al-Mg alloy, and cerium is the highest element of abundance in the rare earths; Color and luster and iron phase are seemingly; But matter is soft, and malleability and ductility are arranged, and can improve the electric conductivity of almag effectively; MnCr is the compound that adds in the Al-Mg alloy, can improve heat treatment performance effectively; Zirconium (Zr) element is the rare earth element that adds in the Al-Mg alloy, and the surface of zirconium is prone to form layer oxide film, has gloss, and outward appearance is similar with steel, and corrosion resistance is arranged, and can improve plasticity effectively, and its intensity is high, and resistivity is stable.
