Product Description
Hafnium wire is drawn by hafnium rod.
Purity: Hf+Zr≥99.95%
Form: wire, straight wire, pellets, 0.5-6*Lmm
Application: Plasma cutting, optical coating
Pure hafnium has plasticity, easy processing, high temperature corrosion resistance, is an important material for atomic energy industry. Large thermal neutron capture cross section of hafnium is an ideal neutron absorber control rods and can be used for protection of the nuclear reactor. Hafnium powder can be used for rocket propulsion. In the electronic industry for producing X-ray tube cathode.
ASTM B737 Standard covers two grades of wrought hafnium and hafnium alloy Rod Wire Hot Rolled or Cold Rolled
Grade R1 for nuclear applications, and Grade R3 for commercial applications.
