PURPOSE:To obtain an Al small-gage wire having excellent bonding properties by selecting the kinds and quantity of addition of elements to be added to Al having high purity. CONSTITUTION:0.5-2.0wt% Mg is added to Al having not less than 99.9% purity, and one kind or two kinds or more of elements of 0.01-0.4wt% Cu, 0.01- 1.0wt% Ag and 0.05-0.2wt% Au are further added by 0.01-1.0wt% in total. When 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 dampproofness and uniform quality. |
