Sondermetall Hafnium Hafnium is always found in minor quantities in Zirconium minerals. Hafnium is a silvery shining metal and very easy to deform as a pure element. The main field of application is the nuclear technology. Due to the high neutron capture cross section Hafnium is used in control-rods for regulation of chain reaction in nuclear reactors.

Significant Characteristics and Applications:
  • high corrosion resistance
  • high neutron capture cross section
  • getter-effect on oxygen and nitrogen
Used as control-rods for nuclear technology, components for lighting technology, alloying element of superalloys, wear-resistant coating and optical coating.

ASTM Standard Specifications:
ASTM B737 (Hot Rolled and/or Cold Finished Hafnium Rod and Wire)
ASTM B776 (Hafnium and Hafnium-Alloy Strip, Sheet and Plate)
