ALUMINUM ALLOY WIRE MANUFACTURING METHOD AND ALLUMINUM ALLOY WIRE

摘要

An aluminum alloy wire manufacturing method comprises (A) a step for melting an aluminum alloy containing 0.40-0.55 mass% of Mg and 0.45-0.65 mass% of Si, the balance being obtained from Al and unavoidable impurities, (B) a step for casting molten metal of the aluminum alloy and rolling to form a rough-drawn wire rod, (C) a step for solutionizing the rough-drawn wire rod, (D) a step for drawing the rough-drawn wire rod after solutionizing to form a drawn wire rod with a wire diameter of 0.5 mm or less, and (E) a step for heat treatment so that internal strain is removed with substantially no deposition of Mg2Si.
