PURPOSE:To obtain an Al small-gage wire having excellent bonding properties by selecting the kinds and quantity of addition of elements added to Al having high purity. CONSTITUTION:0.2-1.0wt% Si and 0.2-1.5wt% Mg are added to Al having not less than 99.9% purity, and one kind or two kinds more of elements of 0.01- 0.5wt% Cu, 0.01-1.0wt% Ag and 0.005-0.2wt% Au are further added by 0.01- 1.0wt% in total. The Al alloy is melted and casted, wire-drawn to form a small- gage wire having a 0.02-0.5mm.phi diameter, and thermally treated (350 deg.C and 30min). An Al small-gage wire obtained has proper tensile strength and adhesive strength, and also has excellent corrosion resistance and uniform quality. |
