| abstract |
The present invention provides a magnesium-lithium alloy having both corrosion resistance and cold workability balanced at high levels, a certain degree of tensile strength, and very light weight, as well as a rolled material and a formed article made of this alloy. The alloy of the invention contains not less than 10.5 mass% and not more than 16.0 mass% Li, not less than 0.50 mass% and not more than 1.50 mass% Al, and the balance of Mg, and has an average crystal grain size of not smaller than 5 µm and not larger than 40 µm, and a tensile strength of not lower than 150 MPa or a Vickers hardness (HV) of not lower than 50. |
