Patent ID: 8308878

Claim:
Magnesium-based alloy wire of composition containing, in mass %, 0.1 to 12.0% Al, and 0.1 to 1.0% Mn; the magnesium-based alloy wire being manufactured by a procedure including a drawing process of drawing a parent material of said composition at a controlled temperature to work the parent material into wire form so as to impact the following properties to the magnesium-based alloy wire: a length L of 1000 d or more, where d is its diameter; a tensile strength of 250 MPa or more; a necking-down rate of 15% or more; a elongation of 6% or more; a crystal grain size of said composition of between 3.5 μm and 10 μm inclusive; and a surface roughness of R z≦ 10 μm.
