Hafnium

Hafnium is a bright silvery ductile metal. It resists corrosion and is chemically similar to zirconium. Hafnium is mainly used in the neutron control systems of nuclear reactors and in submarines, in particular because of its very high neutron absorption capacity (its absorption capacity is about 600 times that of zirconium). In addition, it has strong mechanical properties and excellent corrosion resistance.
