摘要
研究了工业纯铝中加入镁、钙、硅、铁对其导电性的影响 .结果表明 :硅在铝中引起电阻率的增加最大 ,铁最小 ,因此 ,铁是强化铝导体的首选元素 .铝中铁硅质量比在 3 .0~ 3 .8时 。
Alloying effects of Mg, Ca, Si and Fe elements on electrical conductivity of industrial aluminum have been studied. They decrease the conductivity in the sequence of Si, Mg, Ca and Fe. Therefore, the content of Si in the aluminum alloy should be strictly controlled and the Fe element should be the most promising one for strengthening electrical conductive aluminum alloys. Moreover, the optimum m (Fe)/ m (Si) is determined to be in the range of 3.0~3.8.
