Fajar Metals, a well-respected manufacturer and supplier located in Jakarta, Indonesia, specializes in top-notch Copper Nickel 90/10 Coils that are built to last and resist corrosion in marine, industrial, and chemical settings. Crafted from an alloy of 90% copper and 10% nickel, these coils are prized for their exceptional resistance to seawater corrosion, biofouling, and high-temperature oxidation. Offered in a variety of widths, thicknesses, and tempers, Fajar Metals ensures that their Cu-Ni 90/10 coils meet international standards like ASTM B122 and B171. These coils are perfect for creating heat exchangers, condensers, and tubing for tough applications.
The Copper Nickel 90/10 Coil consists of 90% Copper (Cu) and 10% Nickel (Ni), along with trace amounts of Iron (Fe) and Manganese (Mn) to enhance strength and corrosion resistance. This material boasts a tensile strength ranging from 275 to 350 MPa, a yield strength of 105 to 150 MPa, and excellent ductility and weldability. These coils are particularly resistant to chloride-induced corrosion, biofouling, and stress cracking, making them a great choice for marine and industrial uses. Their impressive thermal conductivity, formability, and soldering compatibility also make them ideal for high-performance heat exchange and fluid handling systems.
