Sayam Nickel Alloys, based in Hyderabad, is a trusted manufacturer and supplier of premium nickel-copper welding consumables designed for marine and corrosion-resistant applications. Known for precision manufacturing, consistent quality, and reliable delivery, the company serves industries such as shipbuilding, offshore platforms, desalination, and chemical processing. Its AWS Class ERNiCu-7 SAW and FLUX Welding Wire is engineered for submerged arc welding applications, delivering excellent arc stability, smooth deposition, and superior corrosion resistance. These wires are ideal for heavy-duty welding where high strength and durability in seawater and chemically aggressive environments are critical.
AWS Class ERNiCu-7 SAW and FLUX wires are copper-nickel based, primarily composed of copper with 30% nickel. Minor controlled amounts of iron and manganese improve weld soundness and mechanical performance. The weld metal exhibits good tensile strength, high ductility, and outstanding resistance to seawater corrosion, erosion, and biofouling. The wires ensure smooth arc characteristics, stable deposition rates, and crack-free welds. Their mechanical properties allow them to withstand aggressive marine and industrial conditions, providing reliable performance for large-scale welding applications.

AWS Class ERNiCu-7 SAW and FLUX Welding Wires are widely used for welding copper-nickel alloys such as 70/30 and 90/10 Cu-Ni, as well as joining copper-nickel to carbon steel or stainless steel. They are particularly suitable for submerged arc welding applications in marine and offshore industries due to their excellent resistance to seawater and salt-laden environments. Common applications include ship hull structures, seawater piping systems, condensers, heat exchangers, desalination plants, and offshore platforms. These wires are also ideal for heavy-duty repair welding, where corrosion resistance, weld integrity, and long-term durability are critical for performance and safety.
