Fajar Metals, a well-respected manufacturer and supplier based in Jakarta, Indonesia, specializes in top-notch AWS Class ERNiCu-7 MIG and TIG Filler Welding Wire and Rod, perfect for welding nickel-copper alloys. This filler metal is celebrated for its outstanding resistance to seawater, brine, and various non-oxidizing acids, making it a go-to choice in marine, chemical, and desalination industries. Typically used for welding Monel® alloys and similar nickel-copper materials, ERNiCu-7 offers impressive strength and exceptional resistance to corrosion and cracking. Fajar Metals provides this filler wire and rod in a variety of sizes, ensuring precision, durability, and high-quality weld performance for even the toughest applications.
ERNiCu-7 is a nickel-based alloy that boasts a high copper content, along with small amounts of titanium and iron. The titanium helps manage the grain structure of the weld metal, which minimizes porosity and boosts weld integrity. This filler metal is known for its remarkable resistance to corrosion, especially in saltwater and acidic environments. It retains strong mechanical properties, including high tensile strength, good ductility, and toughness, even under cryogenic and high-temperature conditions. Fajar Metals guarantees consistent arc stability and clean welds for both MIG and TIG processes, making it ideal for fabrication and repair work.
