Abstract

See full text

Provided is a magnesium-lithium alloy which contains 10.5-16.0 mass% Li and 0.50-1.50 mass% Al, the remainder comprising Mg, and which has an average crystal grain diameter of 5-40 µm and a tensile strength of 150 MPa or higher. When a probe including two cylindrical pins in which the distance between the pins is 10 mm and the pin tips have a diameter of 2 mm (contact surface area per pin, 3.14 mm2) is pressed against the surface of the alloy under a load of 240 g, then the surface electrical resistance measured with the ammeter is 1 Ω or less. This alloy is an extremely lightweight alloy which combines corrosion resistance and cold workability on a high level, has a certain degree of tensile strength, and has a reduced surface electrical resistance. Also provided are a rolled material and a molded article both comprising the alloy and a process for producing the alloy.
