Sayam Nickel Alloys, based in Hyderabad, is a trusted manufacturer and supplier of premium copper-nickel welding consumables engineered for marine and corrosion-resistant applications. With a strong emphasis on product reliability, metallurgical expertise, and consistent quality, the company supports industries such as shipbuilding, offshore engineering, desalination, and chemical processing. Sayam Nickel Alloys produces filler wires and rods that ensure smooth arc characteristics and sound weld deposits. Its AWS Class ERCuNi MIG and TIG Filler Welding Wire and Rod are designed for dependable welding of copper-nickel alloys, delivering excellent corrosion resistance and long-term service performance.
AWS Class ERCuNi filler wires and rods are copper-nickel based consumables, with copper as the primary element and balanced additions of nickel to enhance strength and corrosion resistance. Small controlled amounts of iron and manganese may be included to improve weld soundness and mechanical stability. The weld metal offers good tensile strength, high ductility, and excellent resistance to seawater corrosion, erosion, and biofouling. These fillers provide stable arc performance and produce clean, crack-free welds.

AWS Class ERCuNi MIG and TIG filler welding wires and rods are widely used for joining copper-nickel alloys such as 90/10 and 70/30 Cu-Ni, as well as for welding copper-nickel to carbon steel or stainless steel. They are especially suitable for marine and offshore environments due to their outstanding resistance to seawater and salt-laden atmospheres. Typical applications include ship hull structures, seawater piping systems, condensers, heat exchangers, desalination plants, and offshore platforms. These fillers are also ideal for repair and maintenance welding where corrosion resistance and joint reliability are critical.
