[0082] Wire rods of Examples, Comparative Examples, and Conventional Examples were produced as follows. However, the wire rods of Comparative Example 1-No. 12, Comparative Example 3-No. 8, and Comparative Example 3-No. 9 were produced by other methods as will be described later.

[0083] Fe, Mg, Si, Cu, Ti, V, and Al were used in the amounts (mass %) shown in Tables 1 to 4, and the molten metal was continuously cast in a water-cooled mold using a Propez type continuous casting calender. Rolled while casting, made about of bars. The casting cooling rate at this time is 1°C / sec to 20°C / sec.

[0084] Next, surface peeling is performed, making approx. It is subjected to drawing processing in such a manner as to obtain a predetermined degree of processing. Next, as shown in Tables 1 to 4, the processed material after cold drawing was subjected to intermediate annealing at a temperature of 300 to 450° ...

Abstract

The purpose is to provide an aluminum alloy conductor having satisfactory electrical conductivity and tensile strength and excellent bending fatigue resistance. This aluminum alloy conductor has a recrystallized grain structure in which the surface area ratio of crystal grains each having face (111) located in parallel with a cross-section vertical to the rolling direction is 40% or more, and also has a crystal grain diameter of 1 to 30 [mu]m in a cross-section vertical to the rolling direction of a wire material when the conductor is made into the wire material.

Description

【Technical field】 [0001] The present invention relates to an aluminum alloy conductor used as a conductor of an electrical wiring body. 【Background technique】 [0002] Conventionally, as electrical wiring bodies of mobile bodies such as automobiles, trains, and aircrafts, parts called wire harnesses (Wiya-Hanes) in which copper or copper alloys are attached to electric wires containing copper or copper alloy conductors (such as Brass) terminals (connectors), but in recent years, in reducing the weight of mobile bodies, the use of aluminum or aluminum alloys that are lighter than copper or copper alloys as conductors of electrical wiring bodies is being studied. [0003] The relative density of aluminum is about 1 / 3 of that of copper, and the electrical conductivity of aluminum is about 2 / 3 of that of copper (in the case of pure copper as the benchmark of 100% IACS, pure aluminum is about 66% IACS). To flow the same current as a pure copper conductor wire through the wire, t...
