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:0.5-1.5wt% Si is added to Al having not less than 99,9% purity, and one kind or two kinds or more of elements of 0.001-0.3wt% Fe, 0.001- 0.3wt% Ni and 0.001-0.3wt% Co are further selected and added by 0.001- 0.3wt% in total. When the Al alloy is melted and casted, wire-drawn to form a small-gage wire having a 0.5-1.5mm. diameter and thermally treated (350 deg.C and 30min), an Al wire obtained has proper tensile strength and adhesive strength, and also has excellent dampproofness and uniform quality. |
