| description | A 3000 series aluminum alloy sheet which has a heat dissipation characteristic which can be applied to a large-size lithium ion battery container and further which is excellent in formability and shape freezability and furthermore is also excellent in laser weldability is provided. An aluminum alloy sheet which comprises a cold rolled, annealed material which contains Fe: 0.05 to less than 0.3 mass%, Mn: 0.6 to 1.5 mass%, and Si: 0.05 to 0.6 mass%, has a balance of Al and impurities, and has, as impurities, Cu: less than 0.35 mass% and Mg: less than 0.05 mass%, has a conductivity which exceeds 45% IACS, has a 0.2% proof strength of 40 to less than 60 MPa, and displays a 20% or more value of elongation. Further, an aluminum alloy sheet which comprises an as-cold-rolled material which has a conductivity exceeding 45% IACS, a 0.2% proof strength of 60 to less than 150 MPa, and displays 3% or more value of elongation. Still further, to raise the conductivity, one or more of Co: 0.001 to 0.5 mass%, Nb: 0.005 to 0.05 mass%, and V: 0.005 to 0.05 mass% may be included. |
