Zirconium rod

Material: R60702, r60704, r60705, ZR1, Zr2

Executive standard: ASTM b550 ASTM b551 GB / t21183-2007

Zirconium tube is an alloy tube material made of zirconium and other metals. Due to the excellent nuclear and corrosion resistance of zirconium, zirconium alloy tubes and rods are often used in the nuclear fuel assemblies and in core structures of water-cooled reactors. Pure zirconium tubes and rods are mainly used in the manufacture of chemical equipment because of their low costIt's expensive and not much. The chemical composition and application of commonly used zirconium tube and bar are shown in the table, and the amount of zirconium tin alloy tube and bar is more.

Zirconium alloy is a solid solution of zirconium or other metals. Zirconium has very low thermal neutron absorption cross section, high hardness, ductility and corrosion resistance. Zirconium alloys are mainly used in the field of nuclear technology, such as fuel rods in nuclear reactors. Typical compositions of nuclear grade zirconium alloys are more than 95% zirconium and less than 2% tin, niobium, iron, chromium, nickel and other metals, which are added to improve mechanical properties and corrosion resistance.

Zirconium alloy has corrosion resistance and biocompatibility, so it can be used for implantation. In medicine, zr-2.5nb alloy can be made into knee or hip implants. This zirconium alloy material can reduce friction, increase wear resistance, and maintain overall properties (manufacturability, fracture toughness and ductility), providing a good solution for medical implants.
