Be₂W is an intermetallic compound combining beryllium and tungsten, representing a high-performance metallic material from the refractory intermetallic family. This material is primarily of research and advanced engineering interest rather than broad commercial use, valued for applications requiring exceptional stiffness combined with relatively low density. Be₂W is explored in aerospace and defense contexts where weight reduction, thermal stability, and structural rigidity are critical competing demands, though its brittleness and manufacturing challenges limit wider industrial adoption compared to titanium or nickel-based superalloys.
