High Purity Hafnium Metal (Low Zr):

Hafnium metal is produced as a by-product of zirconium refining. An estimated 60 to 70 metric tonnes of the element are produced worldwide each year. The consumption of hafnium is spread across a number of industries, from electronics to nuclear. The largest consumer of the metal, however, are super-alloy manufacturers who use hafnium to improve stress resistant properties of alloys at high temperatures.
