Zirconium 705 Rod (UNS R60705) is a high-performance zirconium-niobium alloy known for its excellent corrosion resistance, high strength, and superior performance in high-temperature and high-pressure environments. As a member of the zirconium alloy family, Zirconium 705 contains small amounts of niobium (2–3%), which significantly enhances its mechanical strength and corrosion resistance compared to commercially pure zirconium grades.

This alloy is widely used in nuclear power, aerospace, chemical processing, and medical applications, where durability, purity, and resistance to aggressive environments are essential. The UNS R60705 rod offers excellent formability and weldability, allowing it to be manufactured into complex shapes for specialised components.
