Rupal Metals, based in Delhi, India, has built a solid reputation as a leading manufacturer and supplier of top-notch Copper Nickel Forgings. Known for their remarkable strength, resistance to corrosion, and precise dimensions, these forgings are crafted from high-quality Cu-Ni alloys. They find their place in various industries, including marine, power generation, oil & gas, and chemical processing. With state-of-the-art production facilities and a commitment to international standards, Rupal Metals ensures that every forging is designed to perform reliably in tough conditions. Clients trust Rupal Metals for high-performance, durable, and custom Copper Nickel forgings tailored to meet their specific industrial needs.
Copper Nickel Forgings are generally offered in two main alloy grades: 90/10 (90% copper, 10% nickel) and 70/30 (70% copper, 30% nickel), often with trace amounts of iron and manganese to boost strength and corrosion resistance. These forgings are known for their outstanding resistance to seawater corrosion, biofouling, and stress corrosion cracking. Their mechanical properties include tensile strength ranging from 275 to 520 MPa, yield strength between 105 and 260 MPa, and elongation of up to 30%. With excellent ductility, weldability, and thermal stability, Copper Nickel forgings maintain their structural integrity even under extreme pressure, temperature, and corrosive conditions.

Compatible welding processes for copper-nickel forgings include TIG (Tungsten Inert Gas), MIG (Metal Inert Gas), and Stick welding. These methods ensure strong, durable joints while preserving the material's properties.
Copper-nickel forgings are commonly used in marine, aerospace, chemical processing, power generation, oil and gas, desalination, and plumbing industries due to their corrosion resistance, strength, and durability in harsh environments.
Factors ensuring the durability of copper-nickel forgings include proper alloy composition, effective heat treatment, corrosion resistance, precise forging processes, and protective coatings, all contributing to strength, reliability, and long-term performance.
Copper Nickel Forgings are widely utilized in marine settings for seawater piping, pump components, valve bodies, flanges, and fittings, thanks to their impressive resistance to saltwater corrosion and biofouling. In the chemical and power sectors, they are essential in heat exchangers, condensers, and high-pressure systems. Offshore oil platforms and desalination plants depend on these forgings for their strength and longevity. Moreover, Copper Nickel forgings are perfect for applications that demand both mechanical performance and resistance to aggressive fluids.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
