摘要
Four kinds of deformed aluminum alloys were tested. One kind of RE-Al-Mg-Si alloy, which possessed high conductivity and strength, was the first priority by contrast test. The large specification bus of conducting aluminum alloys was made by thermomechanical process during the industrial experiment. The properties of the bus are as follows: the tensile strength sigma (b) is 238 MPa, the conductivity (v.s. IACS) is 54.3%, and the current-carrying capacity is beyond 3.1 kA during working process. This kind of RE-Al alloy bus has been applied to several electrical transmitting and transforming work.
