Abstract

An alloy based on magnesium with a load at rupture of at least 290 MPa and an elongation at rupture of at least 5%, the alloy comprising by weight, 2 to 11% aluminum, 0 to 1% manganese, 0.1 to 6% strontium, various possible impurities, and the remainder magnesium. The alloy has a structure including a matrix of fine grains of magnesium of a mean size below 3 .mu.m reinforced by intermetallic compounds dispersed homogeneously at the grain boundairies and having a mean size less than 1 .mu.m, the structure remaining unchanged if kept for more than 24 hours at a temperature up to 300.degree. C.
