Fajar Metals, a top-notch manufacturer and supplier located in Jakarta, Indonesia, specializes in high-quality Copper Nickel 70/30 Fittings that cater to the rigorous demands of marine and industrial sectors. Crafted from a robust 70% copper and 30% nickel alloy, these fittings boast impressive resistance to seawater corrosion, erosion, and biofouling. Fajar Metals offers a wide array of fittings, including elbows, tees, reducers, couplings, and crosses—engineered for durability, reliability, and long-lasting performance. Adhering to international standards like ASTM B466/B467 and ASME guidelines, these fittings are a trusted choice for high-performance systems in offshore, shipbuilding, and desalination applications.
Copper Nickel 70/30 Fittings are composed of an alloy featuring 70% Copper (Cu) and 30% Nickel (Ni), with minor additions of Iron (Fe) and Manganese (Mn) to boost mechanical strength and corrosion resistance. These fittings are celebrated for their outstanding resistance to saltwater, brine, and biofouling, along with commendable thermal conductivity. They generally exhibit a tensile strength ranging from 350 to 450 MPa, a yield strength of 150 to 200 MPa, and possess high ductility and elongation. Their mechanical stability and resistance to stress corrosion make them perfect for high-pressure and high-velocity fluid applications.
