HfZr
metal· JVASP-37802· HfZr
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.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
