ALUMINIUM ALLOY CONDUCTOR AND MANUFACTURING METHOD FOR SAME

摘要

Disclosed is an aluminium alloy conductor which exhibits sufficient tensile strength, flexibility and electrical conductivity, high bend-tolerance fatigue properties and anti-stress relaxation properties, and also has excellent workability. The disclosed aluminium alloy conductor includes 0.01-0.4 mass% Fe, 0.1-0.5 mass% Cu, 0.04-0.3 mass% Mg, and 0.02-0.3 mass% Si, and further includes 0.001-0.01 mass% of a combination of Ti and V, and is formed from the remaining portion (A1) and unavoidable impurities. The aluminium alloy conductor has a crystal grain diameter, in a vertical cross section in the wire drawing direction, of 1-20µm, and a second phase distribution density, having dimensions of 10-200nm, of 1-102 parts/µm2.
