ASTM Zr702 UNS R60702 Zirconium Wire For Nuclear Fuel Assembly

Product Description

ASTM Zr702 UNS R60702 Zirconium Wire For Nuclear Fuel Assembly

Zirconium wire is a further processed zirconium material. Due to the small thermal neutron absorption cross section of metal zirconium, metal zirconium has excellent nuclear properties. Nuclear grade zirconium is used as structural materials of nuclear powered aircraft carriers, nuclear submarines and civil power reactors, cladding of uranium fuel elements, etc. Nuclear grade zirconium can be regarded as an important national strategic metal, which is closely related to the development of nuclear industry.
