Fajar Metals, a well-respected manufacturer and supplier located in Jakarta, Indonesia, specializes in providing high-quality Copper Nickel Fittings designed for exceptional performance in marine, industrial, and offshore settings. These fittings come in Cu-Ni 90/10 and 70/30 grades and are crafted to meet international standards like ASTM B466, B467, and ASME B16.9/B16.11. Fajar Metals offers a comprehensive selection of fittings, including elbows, tees, reducers, couplings, and caps, all ensuring precision, durability, and leak-proof functionality. With their impressive resistance to corrosion, erosion, and stress cracking, these fittings are perfect for saltwater systems, heat exchangers, and other critical piping needs.
Copper Nickel Fittings are made from Cu-Ni 90/10 (90% Copper, 10% Nickel) or Cu-Ni 70/30 (70% Copper, 30% Nickel) alloys, with small amounts of Iron (Fe) and Manganese (Mn) added to enhance mechanical strength and corrosion resistance. Typically, these fittings show a tensile strength ranging from 275 to 420 MPa, yield strength between 105 and 180 MPa, and exhibit high ductility. Their natural resistance to biofouling, pitting, and stress corrosion cracking ensures they provide reliable service in high-salinity and aggressive environments. Plus, their excellent thermal conductivity and weldability make installation and integration into various piping systems a breeze.

Copper-nickel pipes are widely used in marine and offshore applications, due to their excellent resistance to corrosion, especially to sea water, and are commonly found in marine production for marine cooling systems, ballast systems and deck hardware. Technically, these materials are used in heat exchangers, desalination plants, and pharmaceutical applications where corrosion and fouling resistance is required Their durability is important for oil and gas pipelines, and HVSs.
