Description
Zirconium 705 (UNS R60705) is a zirconium-based alloy containing small additions of niobium, titanium, and other alloying elements. It combines excellent strength, corrosion resistance, and oxidation resistance, making it ideal for demanding applications in harsh environments.
Zirconium 705 is widely used in nuclear power generation, aerospace components, and chemical processing equipment due to its ability to withstand high temperatures and aggressive media. It also offers outstanding resistance to stress-corrosion cracking, ensuring durability in critical service conditions.
Zirconium 705 Welding Wire
Zirconium 705 welding wire is specifically designed for welding zirconium and zirconium alloys, particularly Zirconium 705.
It is manufactured in standard diameters ranging from 0.045" to 0.125", suitable for various industrial welding applications.
Zr705 wire can be used in multiple welding processes, including:
Gas Tungsten Arc Welding (GTAW / TIG)
Gas Metal Arc Welding (GMAW / MIG)
Shielded Metal Arc Welding (SMAW)
This alloy provides high weld quality and maintains corrosion and temperature resistance after joining.
