A magnesium based alloy contains zinc, aluminium, calcium and/or beryllium, optionally manganese, and the balance magnesium except for incidental impurities. The zinc and aluminium contents fall within a quadrangle defined by lines AB, BC, CD and DA and the calcium and beryllium contents fall within a quadrangle defined by lines EF, FG, GH and HE wherein: A is 10% Zn-2.5% Al, B is 10% Zn-5% Al, C is 13% Zn-6.4% Al, D is 19% Zn-2.5 % Al, E is 0.01% Ca-0% Be, F is 1% Ca-0% Be, G is 0% Ca-0.0025% Be, and H is 0% Ca-0.0001% Be. |
