Zirconium 702 (UNS R60702) is a commercially pure zirconium alloy that offers outstanding corrosion resistance, excellent ductility, and good mechanical strength. It contains a minimum of 99.2% zirconium and hafnium combined, with small amounts of iron and chromium to enhance strength and corrosion resistance.

Unlike stainless steels, Zirconium 702 is not an austenitic alloy and contains no significant chromium or nickel content. It is a non-magnetic, highly corrosion-resistant metal suitable for use in the most aggressive chemical and nuclear environments.

Zirconium 702 rod is commonly used in nuclear power generation, chemical processing, marine, and aerospace applications, where resistance to strong acids, alkalis, and saltwater environments is critical. The material can be machined, welded, and formed easily while maintaining its structural integrity under extreme operating conditions.

Key Features

Excellent resistance to pitting and crevice corrosion ensures long service life.

2. Nuclear Power Industry

Commonly used for nuclear fuel cladding, reactor internals, and containment systems, owing to its low neutron absorption cross-section and high purity.

3. Aerospace and Defence

Applied in aircraft and missile structures, fasteners, and exhaust systems, where a combination of lightweight strength and corrosion resistance is required.

4. Medical and Pharmaceutical Equipment

Utilised for surgical instruments, implants, and prosthetic devices, benefiting from its biocompatibility and resistance to body fluids.

5. Marine and Industrial Applications

Used in heat exchangers, condensers, marine hardware, and desalination equipment due to its excellent resistance to seawater corrosion.

6. Speciality Uses

Sometimes used in military components and decorative jewellery, valued for its lustre, strength, and corrosion resistance.
