摘要： During edgewise bending that is carried out on an aluminum alloy bus bar made of an aluminum alloy rectangular wire, an edgewise bending portion is heated to a temperature between 100 and 250° C. inclusive, and within 5 minutes after the heating, edgewise bending is carried out. In the aluminum alloy bus bar, the ratio A/B of Vickers hardness A in a heated portion to Vickers hardness B in a non-heated portion is at least 0.8. If necessary, flatwise bending is further carried out on the aluminum alloy bus bar, forming the bus bar into a predetermined shape.

摘要： A hot blow forming method for the aluminum alloy sheet carries out a hot blow forming to an aluminum alloy sheet using a first metal mold being a female mold for forming having a protruding surface portion on an inside surface thereof and a second metal mold for gas introduction. Immediately prior to the hot blow forming, a temperature (T1) of the aluminum alloy sheet and a temperature (T2) of the first metal mold satisfy a relation (T1)−(T2)≧30° C. and the temperature (T2) is equal to or higher than 400° C. In the hot blow forming, the aluminum alloy sheet is made to be brought into contact with at least a part of the protruding surface portion of the first metal mold within 30 seconds from a start of the gas introduction from the second metal mold.

摘要： Provided is an aluminum alloy sheet excellent in formability, strength, and quality of appearance. The sheet is composed of an aluminum alloy containing 1.00 to 2.20 mass % of Fe and 0.10 to 1.00 mass % of Mn, with a balance of Al and unavoidable impurities. The sheet is fabricated by rolling. In each of the 0° direction, 45° direction, and 90° direction relative to the rolling direction, the sheet has a total elongation of 34% or more, and has a 0.01% proof stress of 60 MPa or more after application of 2% uniaxial strain and a subsequent heat treatment at 170° C. for 20 minutes.

摘要： 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.
