一种耐热性好的高导电率软铝单丝及其制备方法
摘要：
本发明提出了一种耐热性好的高导电率软铝单丝及其制备方法，该软铝单丝以纯度≥99.7％的工业纯铝，Al-B中间合金和Al-RE中间合金为原料制得，其包括按质量百分比计的下述组分：B≤0.02％，RE：0.1-0.3％，Si:≤0.07％，Fe:≤0.2％，(V+Ti+Cr+Mn)≤0.012％，其余为Al和不可避免的杂质；RE为La或Ce中的一种或两种，本发明在提高软铝单丝导电率的基础上还大大提高了其耐热性，使软铝单丝更加满足电网建设的需要。
摘要（英）：

The invention provides a high-conductivity soft aluminum monofilament with good heat resistance and a preparation method thereof. The soft aluminum monofilament is prepared from industrial pure aluminum with the purity of more than or equal to 99.7%, Al-B intermediate alloy and Al-RE intermediate alloy, and the Al-B intermediate alloy and the Al-RE intermediate alloy are prepared from the following components of, in percentage by mass, less than or equal to 0.02% of B, 0.1%-0.3% of RE, less than or equal to 0.07% of Si, less than or equal to 0.2% of Fe, 0.012% of (V + Ti + Cr + Mn) and the balance Al and inevitable impurities; and Re is one or two of La or Ce. According to the soft aluminum monofilament, the heat resistance of the soft aluminum monofilament is greatly improved on the basisof improving the electric conductivity of the soft aluminum monofilament, so that the soft aluminum monofilament more meets the requirement of power grid construction.
