Description
Technical field
The present invention relates to a kind of aluminium alloy pole stock,, for the production of electric wire, belong to technical field of electric wires and cables.
Background technology
In wires and cables industry, major part is copper conductor at present.And copper is as a kind of strategic resource, and reserves are few, cost is high, belongs to the highly energy-consuming product, and defect causes and can not be used widely and the anti-intensity of conventional aluminium conductor is little, and creep-resistant property is poor etc.Based on this, the present invention is proposed.
Summary of the invention
Use the shortage of copper resource allocation in order to solve in wires and cables industry, the defect such as the problem that cost is high and conventional aluminium bar resist strong grow less than normal, and creep-resistant property is poor, the invention provides a kind of pole stock of high-performance aluminium alloy for the production of electric wire.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of aluminium alloy pole stock by weight percentage, comprises following composition:
Al 98.91-99.2%
Si 0.08%-0.1%

Zn 0%-0.05%
With B 0.02%-0.04%.
Described Mg and Zn are not 0%.
Described aluminium alloy pole stock is by adding according to the above ratio Si, Fe, Cu, Mg, Zn and B to make in the Al under the hot melt state.
Described aluminium alloy rod electric conductivity is the 59.5-60% of reference material copper IACS.
Described aluminium alloy rod current capacity is 79% of copper.
The shortcomings such as aluminium alloy pole stock of the present invention has solved copper shortage of resources in prior art, cost is high, and is less than normal with the anti-intensity of aluminium alloy, and creep-resistant property is poor, in wires and cables industry and unrivaled use advantage arranged.And have following advantage:
1, make comparisons with the conductor of identical specification, aluminium alloy pole stock of the present invention is 62% of the most frequently used I.A.C.S. (IACS) as the electric conductivity of conductor.The weight of alloy cable is half of copper cable of same current capacity.The cross-sectional area of conductor of alloy cable is long-pending while being 1.5 times of copper core, and its electric property is substantially suitable, therefore instead of copper cable fully.
2, the high-conductivity aluminum alloy pole stock conductor through Alloying Treatment has the thin and firm zone of oxidation of one deck densification.The various forms of corrosion of the special tolerance of this zone of oxidation, can prevent the further oxidation of metal, resists the corrosion of chemical substance.Aluminium alloy has the characteristic of bearing severe environment, and the aluminium alloy pole stock is widely used as the conductor of electric wire.In the environment of corrosion, the erosion resistance of aluminum alloy conductor cable is better than the cable of copper conductor greatly.
3, when aluminium alloy pole stock of the present invention during as aluminium alloy core, the ballistic properties of cable is less by 40% than copper cable, and flexility is higher by 24% than copper cable; The aluminium alloy core cable has good bending property, therefore more easily lays and carries out the terminal connection; The thermal expansivity of aluminium alloy core cable is slightly higher than copper cable, and it expands than copper or shrinks more more.Alloy conductor uses the X alloy transition terminal thoroughly to solve the problem of thermal expansion and the corrosion of copper Al electrochemical of two kinds of metal junctions.
