Hf2Cu is an intermetallic compound combining hafnium and copper, belonging to the class of transition metal intermetallics. This material exhibits significant elastic stiffness and moderate density, making it of interest for high-temperature structural applications and advanced materials research. While not widely commercialized in mainstream engineering, hafnium-copper intermetallics are explored in aerospace and materials science contexts for their potential to provide strength retention at elevated temperatures and resistance to oxidation.
