    Hafnium (Hf) is a lustrous silver grey, ductile, transition metal. Hafnium is found in most Zirconium minerals; it is difficult to separate these two elements due to their chemical resemblance. The Hafnium metal is further purified to crystal bars using the van Arkel/de Boer iodine process.  The crystal bars are then consolidated, electron beam (EB) melted and processed to wires, bars, plates, and other metal forms. Hafnium is traditionally used in high temperature super alloys and nuclear control rods. In high-temperature alloys and polycrystalline nickel-based superalloys, hafnium's high melting point - 2,233°C (4,051°F) - helps strengthen grain boundaries, thus considerably improving both high-temperature creep and tensile strength. In addition, with its high affinity for carbon, nitrogen and oxygen, the metal also provides strengthening through second-phase particle dispersion.
    AEM can manufacuture hafnium alloy with high quality.
