Fajar Metals, a top-notch manufacturer and supplier located in Jakarta, Indonesia, is all about providing high-quality Copper Nickel Flanges that are built to withstand the tough demands of marine and industrial settings. You can find these flanges in both Copper Nickel 90/10 and 70/30 grades, designed specifically for exceptional resistance to seawater corrosion, erosion, and biofouling. Fajar Metals has a diverse range of flange types, including weld neck, slip-on, blind, socket weld, and threaded options. Crafted to meet international standards like ASTM, ASME, and DIN, these flanges guarantee secure, leak-proof connections in critical piping systems across offshore, shipbuilding, and power industries.
Copper Nickel Flanges are made up of Copper (Cu) and Nickel (Ni) in either 90/10 (Cu-90%, Ni-10%) or 70/30 (Cu-70%, Ni-30%) ratios, with a touch of Iron (Fe) and Manganese (Mn) added to boost strength and corrosion resistance. These flanges perform exceptionally well in environments with high salinity, high velocity, and fluctuating temperatures. They boast key mechanical properties like a tensile strength of 350–450 MPa, yield strength of 150–200 MPa, along with impressive elongation and weldability. Their ability to resist pitting, stress corrosion, and thermal fatigue makes them perfect for high-pressure marine and chemical piping systems.

Copper nickel flanges are widely used in marine applications, including shipbuilding, desalination plants, and offshore oil and gas platforms, due to their outstanding sea resistance properties corrosive fluids They for connecting pipes, valves and pumps in systems for handling seawater, salt and other corrosive fluids there are examples. Moreover, these flanges are used in heat exchangers, condensers and electrical appliances, where durability and reliability are required. Their high thermal stability and resistance to biofouling make them particularly desirable for use in harsh environments.
