In order to solve the quality problem that the electrical Al bar has a higher resistivity and a lower tensive strength, the property tests have been made. Through comparative tests and analyses, an effective solution to the problem has been proposed by the way of controlling the Al bar's impurity content of Fe to 0 1%～0 16% and Si to 0 08%～0 11% while maintaining the ratio of Fe to Si between 1 2～1 4. In the meantime, a reasonable forming technology has been adopted to obtain fine grained microstructure,thus the demand for the function index of electrical Al bar can be meeted.
