The aluminum alloy material has various performance indexes of a high-elongation aluminum alloy material for a cable and has excellent heat resistance and corrosion resistance; therefore, the material has higher current carrying capacity.
Description
Technical field
The invention belongs to technical field of electric wires and cables, be specifically related to a kind of rare earth high-iron aluminum alloy conductor material.
Background technology
The copper valency rises suddenly and sharply, use the copper cable high cost, to manufacturing enterprise or the user causes very large economic pressures, but because there are the defectives such as mechanical performance, switching performance and decay resistance be relatively poor in aluminium, can't realize substituting the purpose of copper cable, aluminum alloy materials improves and PROCESS FOR TREATMENT through composition, makes aluminium alloy improve the defective that fine aluminium exists, thereby can realize substituting the purpose, particularly power cable field of copper cable.As disclosing a kind of cable high-elongation aluminum alloy material and preparation method thereof in the patent of invention 200910116635.7 of having authorized, this patent provides all extraordinary aluminum alloy materials and preparation method thereof of a kind of extension property, bending property, creep-resistant property and electrical property, it is best that but heat resistance and decay resistance also do not reach, therefore also require further improvement, develop the more excellent aluminum alloy materials of a kind of performance and come the instead of copper conductor.
Summary of the invention
Goal of the invention: the purpose of this invention is to provide a kind of rare earth high-iron aluminum alloy conductor material, adopt aluminum alloy materials of the present invention not only to have the patent of invention cable with outside the property indices of high-elongation aluminum alloy material, this material has more excellent thermal endurance and decay resistance, thereby has larger ampacity.
Technical scheme: for achieving the above object, the present invention is by the following technical solutions: rare earth high-iron aluminum alloy conductor material is content by weight percentage, it comprises the Fe of following component: 0.4～1.5wt%, 0.3 the rare earth element of～3wt%, 0.01 a kind of or several arbitrarily in the Sc of～0.4wt%, Er, Ca, Sb, Mg, all the other are aluminium and inevitable impurity.
Rare earth high-iron aluminum alloy conductor material, described rare earth element are one or more in Y, La, Ce, Pr, Nd.
Described aluminum alloy materials is content by weight percentage, wherein content of impurities≤0.2wt%.
Described alloy makes by following method:
Founding: under 710～760 ℃ of conditions, alloy is respectively become fractional melting, then add the refining agent refining of effective dose, be incubated casting after 20～40 minutes; Again by half annealing in process: 280～380 ℃ are incubated 4～10 hours, naturally cool to room temperature.The refining agent weight proportion is 23%Na
3AlF
6+ 47%KCl+30%NaCl.
Beneficial effect:
1. the aluminum alloy materials for preparing by the present invention has excellent Qu Xingneng, tensile property, creep-resistant property and pliability.
2. add the rare earth element of 0.3～3wt% in the present invention, its rare earth elements is comprised of one or more in Y, La, Ce, Pr, Nd, Y, La, Ce, Pr, Nd have removal of impurities preferably and improve alloy corrosion resistance can effect.Strengthened accordingly and fine and close because the filling of rare earth element makes surface film oxide, this has improved the corrosion resisting property of platform gold greatly, is no matter that rare earth all is improved the effect of corrosion resisting property in the electrochemical corrosion of the anti-oxidant and normal temperature of high temperature.And this effect is more obvious with corrosion process.This is obviously the Al due to the rare earth of corrosion oxidation process formation
2O
3Film has better anti-corrosion effect.Not only ability general corrosion, and to chloride ion, sodium ion, H
2S, CO
2, SO
2With heavy corrosion conditions such as fluorine ions, effect is preferably arranged.During lower than 0.3wt%, the effect that decay resistance improves is not clearly when percentage composition, when content surpasses 3wt%, is opposite trend.Middle Y also has the stable on heating effect of the alloy of raising.
3. also add one or more elements in Sc, Er, Ca, Sb, the Mg of 0.01～0.4wt% in the present invention, these elements have comparatively significantly effect to the thermal endurance that improves aluminium alloy, the percentage composition that adds 0.01～0.4wt%, can make the long-time running temperature of aluminium alloy bring up to 150 ℃, thereby can significantly improve the ampacity of aluminium alloy, improve the thermal stability of aluminium alloy long-time running.
