High temperature aluminum alloys that can be used at temperatures from about −420° F. (−251° C.) up to about 650° F. (343° C.) are described. The alloys are strengthened by dispersion of particles based on the L12 intermetallic compound Al3X. These alloys comprise aluminum, at least one of nickel, iron and chromium; at least one of scandium, erbium, thulium, ytterbium, and lutetium, and at least one of gadolinium, yttrium, zirconium, titanium, hafnium, and niobium.
