Home > Copper Nickel > Copper Nickel Seamless Pipes
Based in Jakarta, Indonesia, Bulan Pipes and Tubes is a reputable producer and supplier of high-performance copper nickel seamless pipes made to last in industrial and marine settings. These pipes are made precisely to satisfy international standards like ASTM B466, B467, and others, and are well-known for their exceptional resistance to seawater, biofouling, and stress corrosion cracking. Our seamless pipes, which come in different Copper-Nickel grades such as Cu-Ni 90/10 and Cu-Ni 70/30, are perfect for heat exchangers, offshore oil rigs, desalination plants, and shipbuilding. For demanding applications, we offer dependable, superior piping solutions
90/10 (Cu-Ni) and 70/30 (Cu-Ni) alloys are frequently used in the production of copper nickel seamless pipes. 90% copper and 10% nickel make up the 90/10 alloy, with trace amounts of iron and manganese added for increased corrosion resistance. With 70% copper and 30% nickel, the 70/30 alloy is stronger and more resistant to turbulence. Tensile strength of 300–500 MPa, yield strength of 100–200 MPa, and good elongation (≥30%) are typical mechanical characteristics. In saline and industrial settings, these alloys demonstrate outstanding formability, weldability, and long-term durability.
