High Purity Polishing Zirconium Bars Zirconium Round Bar Zirconium 702 Round Rod

Zirconium Round Bar are a further processed zirconium material. Zirconium metal has excellent nuclear properties due to its small thermal neutron absorption cross section. Nuclear grade zirconium is used as a structural material for nuclear-powered aircraft carriers, nuclear submarines, civilian power reactors and uranium fuel components. Cladding and so on. Nuclear grade zirconium is an important strategic metal in China and is closely related to the development of nuclear industry.
