一种高导电率软铝单丝及其制备方法
摘要：
本发明提出了一种高导电率软铝单丝，其包括按质量百分比计的下述组分：B 0.01％-0.02％、Er 0.05％-0.2％、Si≤0.06％、Fe≤0.2％、(V+Ti+Cr+Mn)≤0.015％，其余为Al和不可避免的杂质；本发明提供的高导电率硬铝导线延伸率可达35％，导电率可达63.5％IACS，可降低线路损耗4％以上，本发明提供的制备方法操作简单，可靠性高，适用于流水线生产。
摘要（英）：

The invention provides a high-conductivity soft aluminum monofilament. The high-conductivity soft aluminum monofilament comprises the following components of, in percentage by mass, 0.01%-0.02% of B,0.05%-0.2% of Er, smaller than or equal to 0.06% of Si, smaller than or equal to 0.2% of Fe, smaller than or equal to 0.015% of (V+Ti+Cr+Mn), and the balance Al and inevitable impurities. A high-conductivity hard aluminum conductor provided by the invention has the advantages that the elongation rate can reach 35%, the conductivity can reach 63.5% IACS, and the line loss can be reduced by more than 4%. A preparation method provided by the invention is easy to operate, high in reliability and suitable for assembly line production.
