    Hafnium Pellets

  • Introduction

    Hafnium is a silvery coloured, ductile metal which is found in all minerals containing zirconium. Hafnium is fabricated into ingot form through vacuum arc melting of material into slab form and then rolling into plate and sheet product. Hafnium can be used to control recrystallisation of tungsten filaments but its main application is as control rod material in nuclear reactors due to its ability to absorb neutrons. 
    AEM can provide ranges sizes of hafnium pellets with high quality.       


    Purity Hf+Zr > 99.98%, Zr < 3%
    Density 13.3 g/cm3
    Appearance Silvery
    Melting point 2227 ℃


    Diameter  Length
     0.040″- 0.315''(1.0 mm to 8.0 mm Any desired
    Tolerance: +/-0.004''-0.008'' (+/-0.1-0.2mm) Tolerance: +/-0.020''(+/-0.50mm)


    1. As hafnium has great ability to shed electrons into air and has a high melting point, it is the crucial component of the electrode in plasma cutting.
    2. Hafnium also has strong ability to capture neutron, making it a great material for control rods in the nuclear reactors.
    3. Hafnium is also used as additive to alloys.
