HfNi2Sn is an intermetallic compound combining hafnium, nickel, and tin, belonging to the family of hard metallic intermetallics with complex crystal structures. This material is primarily of research interest for thermoelectric and high-temperature structural applications, where its combination of moderate elastic stiffness and high density makes it a candidate for environments requiring thermal stability and resistance to oxidation. While not yet widely adopted in mainstream engineering, HfNi2Sn and related Hf-based intermetallics are being investigated for waste-heat recovery systems and specialized aerospace/defense applications where conventional alloys reach their performance limits.
