摘要： A continuously cast and rolled sheet of an aluminum alloy having Mg in a content of 3 to 6 % by weight is annealed, followed by strain correction, heat and hold treatment at a given temperature between 240 °C and 340 °C for one hour or more, and slowly cooling treatment, to thereby provide an aluminum alloy sheet having enhanced resistance to stress corrosion cracking and improved shape fixability. The slowly cooling treatment is carried out at a cooling rate chosen from a preset cooling zone corresponding to a preset temperature zone S defined in obliquely lined surrounded form in the accompanying drawing.

摘要： An aluminum alloy sheet for automotive use is provided which comprises a starting aluminum alloy sheet which has an alloy composition containing from 2 to 6 % by weight of Mg, 0.15 to 1.0 % by weight of Fe and from 0.03 to 2.0 % by weight of Mn, and a surface layer disposed over one surface of the starting alloy sheet to be pressed against electrodes for use in welding, the surface layer containing a particulate intermetallic compound which has a particle diameter of 0.5 νm or more and a density of 4,000 pieces of particles per one mm2 or more. The product alloy sheet ensures least deformation of an electrode and stable weldability by means of continuous resistance spot welding.
