An Mg base alloy of this invention is characterized in that Ag is contained in an amount of not more than 1.98 at % as an additive material other than Zn. There is provided an Mg base alloy having not only a practically sufficient strength but good ductility at room temperature to an extent that it has hitherto been unable to be desired and having small anisotropy in strength characteristics.

摘要:
A magnesium alloy member capable of achieving a mechanical strength and a high-temperature fatigue strength sufficient for a compressor for in automotive air conditioners The magnesium alloy member is formed by subjecting a cast material of a magnesium alloy containing, on the basis of mass %, from 0.3% to 10% calcium (Ca), from 0.2% to 15% aluminum (Al), and from 0.05% to 1.5% manganese (Mn), and containing calcium (Ca) and aluminum (Al) at a calcium/aluminum mass ratio of from 0.6 to 1.7, with the balance being magnesium (Mg) and inevitable impurities to plastic working (extrusion processing) at from 250° C. to 500° C. This makes it possible to obtain a magnesium alloy member having a room-temperature 0.2% proof stress of 300 MPa or more and a 150° C. fatigue strength of 100 MPa or greater.
