Rupal Metals stands out as a premier manufacturer and supplier of Copper Nickel 90/10 Forgings, right in the heart of Delhi, India. We cater to a diverse range of clients in the marine, industrial, and offshore sectors. Known for our corrosion-resistant and high-strength non-ferrous metal components, we specialize in precision-forged 90/10 Cu-Ni products designed for the toughest environments. With a blend of 90% copper and 10% nickel, our forgings excel in resisting seawater, biofouling, and erosion. Adhering to strict international standards, we offer custom sizes and shapes tailored to meet each client’s unique needs, ensuring reliability, durability, and top-notch performance in critical applications both locally and globally.
Copper Nickel 90/10 (UNS C70600) is an alloy consisting of 90% copper and 10% nickel, along with small amounts of iron and manganese to enhance strength and corrosion resistance. It provides excellent mechanical properties including tensile strength of 275–350 MPa and good ductility and toughness, especially in marine and brine environments. The alloy is highly resistant to saltwater corrosion, stress corrosion cracking, and biofouling, making it ideal for seawater service. It also exhibits excellent weldability and formability, making it a top choice for forged components in piping and structural systems.
