Abstract
The invention relates to a preparation method of aluminum alloy conductors. The ingredients are composed of, by weight, copper of 1.0-1.1%, molybdenum of 0.1-0.3%, magnesium of 0.3-0.5%, cobalt of 0.01-0.03%, iron of 0.03-0.05%, carbon of 0.001-0.0015%, titanium of 0.003-0.005%, vanadium of 0.003-0.005%, nickel of 0.1-0.3%, tungsten of 0.01-0.03% and the balance aluminum and unavoidable impurities. According to the technical scheme, the strength of the aluminum alloy conductors is improved, the influence to the electric conductivity of the conductors is small, and the toughness of the aluminum alloy conductors is improved.
Description
Technical field
The invention belongs to field of aluminum alloys, refer to a kind of aluminum alloy Preparation Method being used as the aluminium alloy conductor of electric wire especially.
Background technology
Generally, except the transmission electric wire of outdoor, the wire in miscellaneous equipment is all based on copper or copper alloy wire, and this is mainly because in the wire of same diameter, and the wire electric conductivity of copper or copper alloy is far above other metal.Along with the increase of electrical equipment, as the copper of wire or the consumption of copper alloy also increasing, and copper be on the one hand noble metal, and also its density is comparatively large on the other hand, adds the weight of wire, and this contradicts with the energy consumption of reduction mobile equipment.Therefore, the electric conductivity aluminium that also higher and density is little manufactures wire, has obtained and has paid close attention to widely.
But all comparatively copper is low for the intensity of fine aluminium, anti-fatigue performance, toughness etc., therefore fine aluminium can not meet and uses as wire, particularly requiring in the field that the cross section of wire is less.Now had technology to propose, use aluminium alloy manufacture wire, this be due to aluminium alloy there is higher intensity while also there is the requirement that higher anti-fatigue performance can meet intensity in wire.The aluminium alloy of these technology generally includes the elements such as iron, magnesium, silicon, manganese, chromium, and in order to improve the intensity of aluminium alloy, add the elements such as titanium, nickel, copper, although and the interpolation of these elements can improve intensity or the toughness of aluminium alloy, the electric conductivity of aluminium alloy is had substantial degradation.
Summary of the invention
The object of this invention is to provide a kind of aluminium alloy conductor, by the technical program, while raising aluminium alloy conductor intensity, toughness and the electric conductivity of aluminium alloy conductor can be ensure that accordingly.
The present invention is achieved by the following technical solutions:
Aluminium alloy conductor preparation method:
Batching, be by weight percentage, the iron of the magnesium of the copper of 1.0-1.1%, the molybdenum of 0.1-0.3%, 0.3-0.5%, the cobalt of 0.01-0.03%, 0.03-0.05%, the carbon of 0.001-0.0015%, the titanium of 0.003-0.005%, the vanadium of 0.003-0.005%, the nickel of 0.1-0.3%, the tungsten of 0.01-0.03%, surplus is that aluminium and inevitable impurity are prepared burden;
Melting, carries out melting by above-mentioned materials and carries out being cast into aluminum alloy ingot; Cooling keeps 30-50 DEG C/sec of speed to cool to 110-130 DEG C after pouring;
Quench annealing process, process of at the uniform velocity lowering the temperature after aluminum alloy ingot is incubated 1-2 hour in 450-500 DEG C of situation under atmosphere of inert gases; Described cooling rate is 15-20 DEG C/sec.
Wherein titanium, vanadium, tungsten, ferro element are carry out calculating batching in the mode of titanium aluminum alloy, vananum, partinium and ferro-aluminium respectively;
Further, aluminium alloy conductor, its composition is by weight percentage, the copper of 1.02%, the molybdenum of 0.14%, the magnesium of 0.42%, cobalt, the iron of 0.035%, carbon, the titanium of 0.0045%, vanadium, the nickel of 0.22%, the tungsten of 0.015% of 0.0033% of 0.0011% of 0.0123%, surplus is aluminium and inevitable impurity.
The present invention's beneficial effect is compared with the existing technology:
By the technical program, while raising aluminium alloy conductor intensity, very little on the electric conductivity impact of wire, and improve the toughness of aluminium alloy conductor.
