Fajar Metals, a reputable manufacturer and supplier based in Jakarta, Indonesia, specializes in high-quality Copper Nickel 90/10 Flanges designed for durability in tough marine and industrial settings. Crafted from an alloy of 90% copper and 10% nickel, these flanges boast impressive resistance to seawater corrosion, erosion, and biofouling. Fajar Metals offers a diverse range of flange types, including weld neck, slip-on, socket weld, blind, and threaded options, all adhering to international standards like ASTM B151, B122, and ASME B16.5. These flanges are perfect for ensuring secure, leak-free piping connections in high-pressure, corrosive environments.
Copper Nickel 90/10 Flanges are made up of 90% Copper (Cu) and 10% Nickel (Ni), with minor additions of Iron (Fe) and Manganese (Mn) to boost their mechanical strength and resistance to corrosion. They deliver a tensile strength ranging from 275 to 350 MPa, a yield strength of 105 to 150 MPa, and excellent ductility, making them ideal for high-pressure applications. This alloy is particularly resistant to chloride-induced corrosion, pitting, stress corrosion cracking, and biofouling, especially in seawater, brine, and chemical processing fluids. Their outstanding weldability and thermal conductivity further enhance the reliability of piping connections.
