MAGNESIUM-LITHIUM ALLOY, ROLLED MATERIAL AND MOLDED ARTICLE

摘要

Provided are a very lightweight magnesium-lithium alloy having high levels of both corrosion resistance and cold workability and a certain tensile strength, a rolled material and a molded article. The alloy contains from 10.5 mass% to 16.0 mass% Li and from 0.50 mass% to 1.50 mass% Al with the remainder comprising Mg. The alloy has a mean crystal grain diameter from 5 µm to 40 µm, a tensile strength of at least 150 MPa and a Vickers hardness (HV) of at least 50.
