· Al73Re27

Al73Re27 is an intermetallic compound in the aluminum-rhenium system, representing a high-refractory metal addition to aluminum. This material exists primarily in research and development contexts, as the extremely high cost and density of rhenium limit practical industrial deployment; it is studied for potential applications requiring exceptional high-temperature strength and oxidation resistance beyond conventional aluminum alloys.
