HfNi3

HfNi3 is an intermetallic compound combining hafnium and nickel in a 1:3 ratio, belonging to the family of refractory metal intermetallics. This material is primarily of research and development interest rather than widely commercialized, with potential applications in high-temperature structural applications where thermal stability and strength at elevated temperatures are critical. Its use of hafnium—a material valued for neutron absorption and thermal resistance—combined with nickel's ductility and corrosion resistance, positions it as a candidate for extreme-environment engineering, though deployment remains limited and largely experimental.
