Neil Metals, based in Kolkata, India, stands out as a top-notch manufacturer and supplier of high-quality Copper Nickel Forgings, crafted for exceptional performance in tough industrial settings. With a strong emphasis on precision engineering and adherence to international quality standards, Neil Metals provides Copper Nickel forgings in various grades, including 70/30 and 90/10. These forgings are celebrated for their remarkable resistance to corrosion, particularly in saltwater and marine environments. Catering to sectors like marine, offshore, power, and chemical processing, Neil Metals ensures the delivery of robust, custom-forged components, all while prioritizing timely delivery, dependable quality, and a deep commitment to customer satisfaction.
Copper Nickel Forgings typically comprise copper (70–90%) and nickel (10–30%), with minor additions of iron and manganese to boost strength and corrosion resistance. These elements significantly enhance performance in seawater and high-temperature conditions. Mechanically, they boast a tensile strength of 400–600 MPa, yield strength of 150–250 MPa, and elongation of 30–40%. Copper Nickel forgings exhibit excellent mechanical stability, thermal conductivity, and resistance to stress corrosion cracking, making them perfect for harsh, high-pressure environments in marine and industrial systems.

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.
These forgings are widely utilized in industries that demand long-lasting performance under corrosive and high-stress conditions. In the marine and shipbuilding sectors, they find applications in pump components, valve bodies, propeller shafts, and seawater intake systems. Offshore oil and gas facilities depend on them for heat exchangers, manifolds, and seawater piping systems. Power plants incorporate these forgings in condenser systems and cooling water loops. Moreover, they are essential in desalination units, chemical processing plants, and naval defense applications. Their outstanding weldability, resistance to biofouling, and durability make Copper Nickel Forgings the go-to choice for challenging and corrosive environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
