Abstract: An aluminum-alloy material (1) has an Al matrix and second-phase particles dispersed in the Al matrix, wherein the value of a metallographic-structure factor F indicated in Equation (1) below is 0.005 or more. F=A·ρ·L·exp(B·E)  (1) Therein, in the above-mentioned Equation (1), L is the total [μm/μm2] of the perimeters of the second-phase particles, from among the second-phase particles present in an arbitrary cross section, whose circle-equivalent diameters are 0.2 μm or more, ρ is the dislocation density [μm−2], E is the electrical conductivity [% IACS] at 25° C., A and B are correction coefficients determined in accordance with the chemical composition of the aluminum-alloy material, 0.2×10−15≤A≤20×10−15, and 0.1≤B≤1.0.

Abstract: A plate-like electric conductor for a busbar having excellent electric conductivity, strength and bendability, and a busbar formed therefrom.The electric conductor formed from an aluminum alloy plate having a thickness of 0.5-12 mm is obtained by subjecting an aluminum alloy consisting essentially of Fe: 0.05-2.0%; Si: 0.05-0.6%; Cu: 0.01-0.35%; by mass, and the balance comprising Al and inevitable impurities to a hot rolling process. The electric conductor has the electric conductivity of 55-60% IACS, tensile strength not lower than 170 MPa and yield strength not lower than 155 MPa, in the as-rolled state at the room temperature, and does not suffer from cracking upon bending by 90° with an inner bending radius equal to its thickness, while having the electric conductivity of 55-60% IACS, tensile strength not lower than 160 MPa, and yield strength not lower than 145 MPa, after a heat treatment at 140-160° C. for not longer than 1,000 hours.

Abstract: An aluminum-alloy clad material includes a skin layer clad to and covering at least one surface of a core layer. The core layer is composed of an aluminum alloy containing Cu: 3.8-4.9 mass %, Mg: 1.2-1.8 mass % and Mn: 0.3-0.9 mass %. The core layer has an area number density of microvoids that have a circle-equivalent diameter of 0.5 μm or greater that is 100/mm2 or less. The skin layer has an Al purity of 99.5 mass % or greater. A method of manufacturing a wrought material from such an aluminum-alloy clad material includes heating the wrought material to the solution heat treatment temperature of the core layer at a temperature-rise rate of 50° C.-200° C./h.
