PURPOSE:To obtain an Al small-gage wire having excellent joining characteristics by the addition of small amounts of two kinds of selected elements by the synergism of the addition by adding the elements to Al having high purity. CONSTITUTION:0.0015-0.005wt% Si and 0.0015-0.005wt% Mg are added to Al having not less than 99.9% purity, and both contents are kept within a range of 0.003-0.008wt%. When the Al alloy is melted and casted, wire-drawn to form an Al wire having 0.1-0.5mm.phi diameter and thermally treated (350 deg.C and 30min), the Al wire obtained simultaneously has tensile strength and hardness proper to joining. |
