Renowned for their commitment to quality and precision, Fajar Metals provides electrodes that adhere to international standards for durability, corrosion resistance, and welding efficiency. The ENiCu-7 electrodes ensure a smooth arc, minimal spatter, and outstanding weld metal quality, even in tough marine and chemical settings. These electrodes are widely used in industries like shipbuilding, desalination, and offshore oil & gas, making them a go-to choice for welding 70/30 and 90/10 Cu-Ni alloys. Fajar Metals guarantees a dependable supply and expert technical support for even the most demanding applications.
ENiCu-7 Coated Electrodes are crafted with a nickel core, enhanced by copper, iron, and trace amounts of manganese and titanium. Tailored specifically for welding copper-nickel alloys, these electrodes deliver weld deposits that boast impressive resistance to seawater corrosion and stress cracking. Typically, the tensile strength of the deposited metal ranges from 60,000 to 70,000 psi, offering good elongation and ductility. The coating promotes stable arc performance, effortless slag removal, and smooth weld beads. These electrodes are versatile enough for all welding positions, ensuring high-quality results on piping, fittings, and structural components in corrosive environments.
