UNS R60705 ZR705 Zirconium Bar Alloy Rod For Nuclear Fuel Assembly

UNS R60705 ZR705 Zirconium Alloy Rod For Nuclear Fuel Assembly

Zirconium alloy rod is a further processed zirconium material. Due to the small thermal neutron absorption cross-section of metallic zirconium, metallic zirconium has excellent nuclear performance. Nuclear-grade zirconium uses this feature as a structural material for nuclear-powered aircraft carriers, nuclear submarines, and civil power reactors, as well as uranium fuel elements. Cladding and so on. Nuclear-grade zirconium can be regarded as an important strategic metal of the country and is closely related to the development of the nuclear industry.

Industrial grade zirconium is mainly used to make chemical acid and alkali resistant equipment, military industry, electronics industry, pipeline valve materials, special high-strength and high-temperature alloy materials, electric vacuum and getter in lighting bulb industry.

Product Features of Zirconium alloy rod

Zirconium alloy rod has excellent corrosion resistance, it has very good corrosion resistance to most organic acids, inorganic acids, strong alkalis and some molten salts. Hydrochloric acid, nitric acid and organic acids near 100°C have no effect on zirconium. Zirconium has better corrosion resistance in alkali than titanium,
