Fajar Metals, a trusted manufacturer and supplier located in Jakarta, Indonesia, provides top-notch Copper Nickel 90/10 Tubing designed for tough marine, offshore, and industrial uses. Made up of 90% copper and 10% nickel, this tubing is celebrated for its outstanding resistance to seawater corrosion, erosion, and biofouling. Fajar Metals offers Cu-Ni 90/10 tubing in various sizes and wall thicknesses, adhering to international standards like ASTM B111 and MIL-T-16420. Perfect for seawater systems, heat exchangers, and condenser tubing, these tubes ensure a long service life, impressive thermal conductivity, and reliable performance even in high-pressure situations.
Copper Nickel 90/10 Tubing consists of 90% Copper (Cu) and 10% Nickel (Ni), with small amounts of Iron (Fe) and Manganese (Mn) added to boost strength and corrosion resistance. This alloy excels in resisting saltwater, brine, and flow-induced corrosion, particularly in high-velocity marine environments. The tubing typically boasts a tensile strength of 275–350 MPa, yield strength of 105–150 MPa, and high ductility along with excellent thermal conductivity. It also has favorable fabrication properties, making it easy to bend, flare, and weld for customized marine and industrial applications.
