Abstract
The invention provides an aluminum alloy material for cables. The aluminum alloy material comprises, by weight, 0.3%-1.0% of iron, 0.02%-0.2% of silicon, 0.1%-1.0% of copper, 0.001%-0.2% of boron, aluminum and inevitable impurities. Compared with a copper conductor with equivalent electrical properties, an aluminum conductor made of the aluminum alloy material is provided with high flexibility, low rebound resilience and good mechanical properties.
Description
Technical field
The present invention relates to a kind of aluminum alloy materials for cable.
Background technology
When selecting the cable conductor material, usually can consider conductivity, formability and the intensity of material.In fact, the bending property of cable conductor is also an importance that affects fitting operation and be convenient to be electrically connected.Such as in terminal box, when the installing space that panel board etc. are less carries out the fitting operation of cable conductor, because installing space is less, may need with the cable conductor bending, to hold required whole cable conductors.Again such as, when cable conductor is arranged on some irregular spaces, also need with cable conductor bending, to adapt to the profile in space.The bending property of cable conductor further relates to again two aspects: pliability and resilience.The pliability of cable conductor shows, and cable conductor is crooked and do not make its complexity that fractures, and is namely for the higher cable conductor of pliability, required it is crooked and power that do not fracture is just less.The resilience of cable conductor shows after the power that it is crooked discharges, the recovery degree of the cable conductor of bending part, and namely for the higher cable conductor of resilience, after its crooked power was discharged, the angle that the part that is bent is restored resilience was larger.In practical operation, comparatively desirable, be can as far as possible for a long time stably keep this degree of crook with less power again after with the cable conductor bending, so wish that cable conductor has than high-flexibility with than low-repulsion.
China uses more cable to use copper as cable conductor at present, and the use of aluminium alloy is simultaneously constantly increasing fast.Copper conductor conducts electricity very well, but price is more expensive.And the density of copper is large, and bending property is not good, so conductor is not easy to connect, can't satisfy the development need of electrical system.Low price and the good bending property of considering aluminium as cable conductor and use aluminium alloy.But fine aluminium is all undesirable as the cable conductor strength of materials and conductivity.Having the lower and intensity of the common intensity of aluminium of high conductivity is easy to descend along with the rising of temperature and creep and lax occurs.Although the intensity of fine aluminium can be strengthened to some extent by cold working, cold working can cause the reduction of formability again, must form aluminium alloy to reach the balance of conductivity, formability and intensity by other metal so add in aluminium.
Therefore, in each component in the design aluminium alloy, consider the possibility of the desired bending property that reaches, electrical characteristic, mechanical strength and the creep relaxation of finished product.Based on above consideration, the invention provides a kind of aluminum alloy materials for cable, the aluminium alloy conductor of making by this aluminum alloy materials is compared with the copper conductor with equivalent electrical characteristic to have than high-flexibility with than low-repulsion and more be difficult for creep relaxation, connects and installs reliably thereby more easily carry out terminal.
Summary of the invention
The purpose of this invention is to provide a kind of aluminum alloy materials for cable, the aluminium alloy conductor of making by this aluminum alloy materials is compared with copper conductor to have than high-flexibility with than low-repulsion, with the installation that is adapted at different occasions be connected needs.
According to an aspect of the present invention, a kind of aluminum alloy materials for cable is provided, content by weight percentage, it comprises following component: content is the iron of 0.3%-1.0%, content is the silicon of 0.02%-0.2%, content is the copper of 0.1%-1.0%, and content is the boron of 0.001%-0.2%, aluminium and inevitable impurity.
More preferably, according to aluminum alloy materials provided by the invention, content by weight percentage, at least satisfy at least one in following constituent content scope, the content of iron mostly is 0.8% most, and the content of silicon mostly is 0.1% most, the content of boron mostly is 0.04% most, and the content of copper mostly is 0.15%-0.3% most.
More preferably, according to aluminum alloy materials provided by the invention, further comprise, content by weight percentage, content mostly are 0.05% magnesium and content most and mostly are most at least one in 0.05% zinc.Remove other element outside the above element, the content summation of other element mostly is 0.1% most, and the content of every kind of element in other element mostly is 0.03% most.
Embodiment
Embodiment 1

The aluminium alloy conductor of this component has satisfied at annealed condition (O), and under hardening state (H14, H19), ANSI (ANSI) is to the machinery of conductor and the requirement of electrical characteristic.Aluminium alloy conductor in the present embodiment has following character:
Embodiment 2
More preferably, on the basis of embodiment 1, content by weight percentage, the content of iron mostly is 0.8% most.The content of silicon mostly is 0.1% most.The content of boron mostly is 0.04% most, and the content of copper mostly is 0.15%-0.3% most.
At first, have for use the aluminium alloy conductor that the aluminum alloy materials of such component is made, with it with the copper conductor with equivalent electrical characteristic and this aluminium alloy conductor during with identical bend radius equal angular, at any temperature, the required strength of the aluminium alloy conductor that uses above-mentioned aluminum alloy materials to make is all less than the required strength of crooked copper conductor.
Secondly, with this aluminium alloy conductor and copper conductor with equivalent electric property with identical bend radius equal angular after, the angle of this aluminium alloy conductor resilience is less than the angle of copper conductor resilience.
The 3rd, by test, the present inventor finds, uses the data of each index of the aluminium alloy conductor that above-mentioned aluminum alloy materials makes along with the variable quantity of variations in temperature, is significantly less than the respective change amount of the copper conductor with equivalent electrical characteristic.
