Abstract
The invention provides a rare earth aluminium alloy conductor. The rare earth aluminium alloy conductor comprises following raw materials by weight percentage: 8.4-8.6% of Zn, 2.2-2.4% of Mg, 2-2.2% of Cu, 0.05% of Fe, 0.05% of Si, 0.15% of Er, 0.25% of Y and 0.2% Gd, and the left raw materials are aluminium. A cable which adopts the conductor in the invention has excellent electric performance, heat resistance performance, wear resisting performance and corrosion resisting performance, and is safer and more reliable when being used as a conductive wire.
Description
Technical field
The present invention relates to technical field of electric wires and cables, relate in particular to a kind of rare earth aluminum alloy conductor.
Background technology
Copper valency rises suddenly and sharply, use copper conductor high cost, Shi Gei manufacturing enterprise or user cause very large economic pressures, but because aluminium exists the defects such as mechanical performance, switching performance and decay resistance be poor, cannot realize the object that substitutes copper cable, aluminum alloy materials improves and PROCESS FOR TREATMENT through composition, makes aluminium alloy improve the defect that fine aluminium exists, thereby can realize the object, particularly power cable field of instead of copper wire.Although have much the patent about the wires of aluminium alloy, combination property is not fine, the synthtic price index of solution electrical property that could not system, corrosion-resistant, wear-resisting and heat resistance.
Summary of the invention
The object of the present invention is to provide a kind of rare earth aluminum alloy conductor, adopt the cable of this conductor to there is excellent electrical, thermal endurance, wear-resisting and decay resistance, as wire, use more safe and reliable.
The technical solution adopted in the present invention is: a kind of rare earth aluminum alloy conductor, and the raw material of rare earth aluminum alloy conductor and percentage by weight are:
Zn 8.4-8.6%, Mg 2.2-2.4%, Cu 2-2.2%, Fe 0.05%, Si 0.05%, Er 0.15%, Y 0.25%, Gd 0.2%, all the other are aluminium.
Rare earth element is one or more compositions in Er, Y, Gd.
Fine aluminium is melted in the well-type electric furnace of 30KW, and temperature remains on 720 ℃, adds successively copper, magnesium, zinc, iron, silicon, yttrium, erbium, gadolinium in the aluminium of molten condition, stirring, refining, slagging-off, and sample analysis after 30 minutes is cast aluminium alloy cast bar in milling train; Aluminium alloy cast bar is carried out to stress annealing at 550-650 ℃, then cast bar is imported to milling train, import 400 ℃ of rolling mill temperatures, then push slivering, cooling, be drawn into aluminium alloy conductor.
The invention has the beneficial effects as follows and adopt the cable of this conductor to there is excellent electrical, thermal endurance, wear-resisting and decay resistance, as wire, use more safe and reliable.The rare earth element of selecting can improve decay resistance and the mechanical property of aluminium alloy preferably.
