HfPt is an intermetallic compound combining hafnium and platinum, belonging to the family of refractory metal alloys designed for extreme-temperature applications. This material is primarily of research and specialized industrial interest, valued for its combination of high melting point, density, and elastic stiffness—properties inherited from both constituent elements. While not yet widely commoditized, HfPt and similar hafnium-platinum systems are investigated for aerospace, nuclear, and high-temperature structural applications where conventional superalloys reach their limits.
