· JVASP-16762· Al2W

Al₂W is an intermetallic compound combining aluminum and tungsten, belonging to the family of refractory metal aluminides. This material is primarily of research and developmental interest rather than a widely established industrial commodity, as intermetallics in this system are investigated for high-temperature structural applications where enhanced stiffness and density are beneficial. Al₂W and related aluminum-tungsten phases are explored in aerospace and high-temperature engineering contexts where improved performance over conventional aluminum alloys or pure tungsten is sought, though practical deployment remains limited due to processing challenges and brittleness typical of intermetallic compounds.
