A magnesium alloy containing Al, Sr, Ca, and Mn, with the balance being Mg and inevitable impurities, the magnesium alloy having: a structure having an &#x3b1;-Mg phase, and a precipitate dispersed in at least one of a grain boundary of the &#x3b1;-Mg phase and a cell boundary, the precipitate including: at least one phase selected from a group A consisting of an AlSr phase, an AlSr phase, a (Mg, Al)Sr phase, and a (Mg, Al)Sr phase; and at least one phase selected from a group B consisting of an AlCa phase and a (Mg, Al)Ca phase, the magnesium alloy having, in a cross section, a total area rate of a group A precipitate and a group B precipitate of greater than or equal to 2.5% and less than or equal to 30%.

Magnesium alloy and magnesium alloy member

A magnesium alloy is provided that includes: 5.0 mass % or more and 15.0 mass % or less of Al; 2.5 mass % or more and 7.0 mass % or less of Sr; 0.05 mass % or more and less than 3.0 mass % of Ca; and 0.1 mass % or more and 0.6 mass % or less of Mn, with a remainder including Mg and inevitable impurities.

Magnesium alloy

An Al&#x2014;Mg&#x2014;Si-based aluminum alloy includes 0.015 to 0.12 mass % of Sr, the aluminum alloy producing a cast metal structure in which MgSi is crystallized in a fine agglomerate form.
