Al Vishwas Nickel Alloys distinguishes itself as a premier manufacturer and supplier of AWS Class ERNiCu-7 MIG and TIG Filler Welding Wire and Rod, serving industries throughout Dubai, UAE, and beyond. The company has established a strong reputation for supplying high-quality welding consumables engineered for durability, corrosion resistance, and reliable weld performance. The ERNiCu-7 filler materials are purpose-built for use with copper-nickel alloys, making them well suited for applications where outstanding resistance to seawater, brine, and sulfide corrosion is essential. Equipped with advanced manufacturing facilities and stringent quality assurance measures, Al Vishwas Nickel Alloys guarantees that their filler solutions not only comply with international welding standards but also serve critical marine, offshore, and industrial applications.
ERNiCu-7 MIG and TIG Filler Wire and Rod, classified under AWS Class, are chiefly composed of a copper-nickel alloy featuring 65% Cu, 30% Ni, together with precisely regulated quantities of Mn, Fe, and other trace elements that improve weldability and corrosion resistance. These fillers deliver remarkable mechanical properties, including high tensile strength, good ductility, and exceptional resistance to seawater, stress corrosion cracking, and erosion. The weld deposits are strong, resistant to cracking, and preserve their structural integrity even under changing thermal conditions, guaranteeing sturdy and reliable welds for the toughest marine and industrial settings.
