Rolling workability, age-hardening and mechanical properties of Mg-5 to 16 mass%Li-1 mass%Al alloys were studied. The limit of reduction for cold rolling of the alloys containing 16 mass%Li exceeds 99.9%. The α+β phase alloys at 8, 10 and 11 mass%Li and the β phase alloy at 16 mass%Li are age-hardenable. A remarkable decrease in elongation is encountered for the β phase alloy having the maximum hardness. Fine platelet precipitates are observed by transmission electron microscopy in the age-hardened 8 mass%Li alloy.
