Description

一种铝合金电缆
技术领域:
本发明涉及电线电缆,尤其是一种铝合金电缆。 
背景技术:
电线电缆的导体材质通常为铜、铝、铝合金三种,全球是贫铜富铝的资源现状,而铜资源越来越稀缺,尤其是我国70%以上的铜材依靠进口,铜价目前已是铝价的3倍以上,所以以铝节铜就迫在眉睫,但是铝导体在实际应用中就是柔韧性很差,多次弯曲后容易断裂,抗蠕性差、抗拉强度差、延展性差等缺陷,使得铝芯电缆事故频发,因此很多重要的易燃易爆场所限制铝芯电缆的使用。 
8000系列铝合金导体不同于以往的纯铝导体,通过在纯铝材料的基础上添加了铜、铁、镁、硅和稀土元素等多种元素,经过特殊的工艺合成和退火处理等先进工艺,克服了纯铝电缆的不足,机械性能与铜基本接近。近年来我国快速采用了这种技术,广泛应用到各行各业中,但是,现有技术生产的铝合金导体的电导率、耐热性、稳定性、抗拉强度等指标在某些领域尚不能满足要求。 
发明内容:
本发明为了解决现有技术问题提供一种高电导率、高耐热性、高稳定性、高抗拉强度的铝合金电缆。 
为解决以上技术问题,本发明所述的一种铝合金电缆,在于包括下述重量百分比的元素:0.02%-0.04%的铜,0.003%-0.03%的硼,0.04%-0.06%的铁,0.001%-0.05%的铬,0.001%-0.05%的锰,0.002%-0.03%的镁,0.001%-0.03% 的镍,0.08%-0.15%的硅,0.001%-0.06%的钛,0.001%-0.03%的钒,0.005%-0.05%的锌,0.001%-0.01%的锆,0.05%-0.15%的稀土元素,余量为铝以及不可避免的杂质。 
优选:0.005%-0.03%的镁。 
优选:0.004%-0.01%的镍。 
优选:0.001%-0.01%的钒。 
本发明的突出优点之一在于铜、镁、铬、铁等合金化元素的加入,特别是其特定含量的配比,使得铝合金电导率、抗拉强度、耐热性和稳定性都得到了提高。 
具体实施方式
实施例一: 
0.025%的铜,0.015%的硼,0.045%的铁,0.02%的铬,0.02%的锰,0.008%的镁,0.008%的镍,0.10%的硅,0.02%的钛,0.02%的钒,0.02%的锌,0.004%的锆,0.08%的稀土元素,余量为铝以及不可避免的杂质。 
余量为铝及不可避免的杂质。 
实施例二: 
0.035%的铜,0.02%的硼,0.05%的铁,0.04%的铬,0.04%的锰,0.02%的镁,0.02%的镍,0.15%的硅,0.04%的钛,0.025%的钒,0.035%的锌,0.008%的锆,0.12%的稀土元素,余量为铝以及不可避免的杂质。 
申请人声明,本发明通过上述实施例来说明本发明的详细组成和工艺流程,但本发明并不局限于上述详细组成和工艺流程,即不意味着本发明必须依赖上述详细组成和工艺流程才能实施。所属技术领域的技术人员应该明了,对本发明的任何改进,对本发明产品各原料的等效替换及辅助成分的添加、 具体方式的选择等,均落在本发明的保护范围和公开范围之内。
