Problems solved by technology

[0004] However, it is known that pure aluminum such as aluminum alloy conductors for power transmission lines (A1060, A1070 according to JIS standards) generally has poor tensile durability, impact resistance, and bending properties.
Therefore, it cannot withstand, for example, unexpected loads applied by workers, industrial equipment, etc. during installation to the vehicle body, stretching of the crimping parts at the connection parts of wires and terminal

Embodiment 1

[0088] Mg, Si, Fe, and Al, and optionally added Mn, Ni, Ti, and B were contained in the contents (mass %) shown in Table 1, using a Propezer-type continuous casting and rolling machine, while utilizing water-cooled casting. The mold continuously casts molten metal and rolls it to make approx. of bars. The casting cooling rate at this time was about 15° C. / s. Next, it was wire-drawn at the processing rate of each round shown in Table 2. Then, the processed material subjected to wire drawing was subjected to intermediate heat treatment (intermediate annealing) under the conditions shown in Table 2, and then wire drawing was performed to make it Next, solution treatment is performed on the workpiece. It should be noted that, in the solution heat treatment, when the batch type heat treatment is used, a thermocouple is wound around the wire rod to measure the temperature of the wire rod. In the continuous energization heat treatment, it is difficult to measure the part with th...
