Hafnium Wire

Eagle Alloys Corporation is an ISO Certified Corporation and have been supply the highest quality Hafnium wire for over 35 years.  EAC can offer a wide variety of sizes in Hafnium wire and can supply custom wire sizes with short lead times.

Eagle Alloys Corporation can supply Hafnium wire from 0.003” Dia up to 0.124” Dia.  For larger diameters EAC can supply Hafnium rod and bar  as large as 10” Dia.  If you do not see your Hafnium wire size listed below, please contact our courteous sales team to assist you. Eagle Alloys supplies DRC Conflict Free material.  EAC only sources our Hafnium wire from Level 1 smelters.

Hafnium is typically supplied to meet the requirements of Hafnium (Hf), 99.5%Hf (2N5), 99.9%Hf (3N), ASTM-B-776 Grade R1 or Grade R3, ASTM-B-737 Grade R1 or Grade R3. Hafnium wire applications include nuclear reactors, nuchttps://www.eaglealloys.com/hafnium/lear submarines, medical treatment equipment, fuel cells, solar energy.

Hafnium has good corrosion resistance and high strength. It resists corrosion due to formation of a tough, impenetrable oxide film on its surface. Hafnium is unaffected by alkalis and acids, except hydrofluoric acid. Hafnium is difficult to separate form zirconium, because the two elements have atoms that are the same size.  Hafnium and its alloys are used for control rods in nuclear reactors and nuclear submarines because hafnium is excellent at absorbing neutrons and it has a very high melting point and is corrosion resistant. It is used in high-temperature alloys and ceramics, since some of its compounds are very refractory: they will not melt except under the most extreme temperatures.
