Zirconium tube rod is an alloy tubular material made of zirconium and other metals. Due to the excellent nuclear performance and corrosion resistance of zirconium, zirconium alloy tubes and rods are often used in nuclear fuel assemblies and reactor structures of water-cooled reactors. They are important nuclear materials.

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

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