Santner Nickel Alloys, based in Hamilton, New Zealand, is a trusted manufacturer and supplier of AWS Class ERCuNi MIG and TIG Filler Welding Wire and Rod. These high-quality filler materials are specifically engineered for joining copper-nickel alloys, providing excellent corrosion resistance, reliable weld strength, and superior mechanical performance. Manufactured under strict quality control, ERCuNi wires and rods ensure smooth arc stability, consistent deposition, and strong metallurgical bonding. Widely used across marine, chemical processing, desalination, and offshore industries, AWS Class ERCuNi filler materials enable durable, defect-free welds in environments exposed to seawater, corrosive chemicals, and high operational demands.
AWS Class ERCuNi MIG and TIG Filler Welding Wire and Rod are primarily composed of copper and nickel, with trace elements that enhance corrosion resistance, ductility, and weldability. These fillers provide excellent tensile strength, toughness, and stability under both thermal and mechanical stress. ERCuNi ensures smooth, crack-resistant weld deposits with minimal porosity and superior metallurgical compatibility when joining copper-nickel alloys. Its balanced composition allows for reliable performance in aggressive marine and chemical environments, maintaining structural integrity and durability even under prolonged exposure to seawater, brine, and other corrosive media.
