一种高导电率中强耐热铝合金单丝及其制备方法
摘要：
本发明涉及电力行业输电线路架空导线技术领域。本发明提供了一种高导中强耐热铝合金单丝及其制备方法，铝合金导线由Zr：0.01～0.1％，B：0.01～0.2％，Si：0.01～0.2％，Fe：0.05～0.3％，Mn：0.2～0.5％，Er：0.01～0.15％和/或Y：0.01～0.15％，V、Ti、Cr中任意2种或3种元素，其余为Al和不可避免的微量杂质组成，其中V：0.1～0.15％，Ti：0.01～0.05％、Cr：0.1～0.15％。本发明制备的铝合金单丝导电率高、耐热性好，抗拉强度大。
摘要（英）：

The invention relates to the technical field of a power industry electric transmission line overhead conductor. The present invention provides a high conductivity moderately strong heat-resistant aluminum alloy monofilament and a preparation method thereof. The aluminum alloy conductor includes: 0.01-0.1% of Zr, 0.01-0.2% of B, 0.01-0.2% of Si, 0.05-0.3% of Fe, 0.2-0.5% of Mn, 0.01-0.15% of Er and/or 0.01-0.15% of Y, any two or three elements selected from the group consisting of V, Ti and Cr, and the balance being Al and inevitable trace impurities, wherein 0.1-0.15% of V, 0.01-0.05%of Ti, and 0.1-0.15% of Cr are included. The aluminum alloy monofilament prepared by the present invention is high in electrical conductivity, good in heat resistance, and high in tensile strength.
