Product Description
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.
Key Features
High corrosion resistance in acids, alkalis, and seawater environments
Excellent strength and stability under high temperatures
Low neutron absorption makes it ideal for nuclear applications
Good biocompatibility, suitable for medical and implant use
Easily fabricated by forging, machining, and welding processes

Applications of Zirconium 705 Rod
1. Nuclear Power Industry
Used for fuel rod cladding, pressure vessels, and heat exchangers due to its low neutron absorption and excellent corrosion resistance in high-temperature water and steam.
2. Chemical Processing
Ideal for pumps, valves, and reactor linings exposed to strong acids and corrosive environments.
Provides long service life and reduced maintenance costs.
3. Aerospace and Defence
Employed in rocket engine components, aircraft exhaust systems, and thermal shields, where high temperature strength and oxidation resistance are required.
4. Medical Applications
Utilised in surgical implants, including artificial heart valves and orthopaedic devices, due to its excellent biocompatibility and resistance to body fluids.
5. Industrial and Marine Uses
Suitable for heat exchangers, condensers, marine hardware, and heat shields, providing durable performance in seawater and corrosive atmospheres.
