HfZr is a binary metal alloy composed of hafnium and zirconium, two refractory transition metals with similar crystallographic properties and high melting points. This material combines the corrosion resistance and neutron absorption characteristics of both constituents, making it valuable in extreme-temperature and nuclear applications where conventional alloys fail. Engineers select HfZr systems primarily for aerospace propulsion components, nuclear reactor control systems, and specialized high-temperature structural applications where resistance to oxidation and thermal cycling is critical.
