· JVASP-67909· BeFe2Cu

BeFe2Cu is an intermetallic compound combining beryllium, iron, and copper in a defined stoichiometric ratio. This material belongs to the family of high-strength intermetallics and is primarily of research and specialized industrial interest rather than a commodity engineering material. It is explored in aerospace and high-performance applications where the combination of beryllium's low density with iron and copper's strengthening effects could provide weight-critical solutions, though processing challenges and beryllium's toxicity limit widespread adoption compared to conventional titanium or nickel-based alternatives.
