These products are celebrated for their remarkable strength, durability, and resistance to corrosion. Crafted to meet international standards like ASTM B122 and B171, these forgings are perfect for demanding marine and industrial environments. Dhruv Metals offers a diverse array of forged components, including flanges, rings, shafts, and custom shapes, all produced using cutting-edge forging technology and strict quality control measures. With a strong focus on precision engineering, timely delivery, and customer satisfaction, Dhruv Metals caters to a variety of industries both locally and globally.
Copper Nickel 90/10 Forgings (UNS C70600) are made up of roughly 90% copper and 10% nickel, with minor additions of iron (1.5%) and manganese (1.0%) to enhance strength and corrosion resistance. These forgings boast impressive mechanical properties, featuring a tensile strength of 310–350 MPa, yield strength of 105–140 MPa, and elongation of 30–45%. The alloy is highly resistant to seawater corrosion, biofouling, and stress corrosion cracking. Additionally, it offers good weldability, high ductility, and stability under high-pressure and high-temperature conditions, making it perfect for demanding, long-term applications.

Copper Nickel 90/10 forgings may face challenges like higher cost, susceptibility to galvanic corrosion in specific environments, and limited availability in some sizes, requiring precise processing and material sourcing.
Common welding processes compatible with Copper Nickel 90/10 forgings include TIG (GTAW), MIG (GMAW), and SMAW. Proper filler materials, such as CuNi rods, ensure strong, corrosion-resistant welds for optimal performance.
Durability of Copper Nickel 90/10 forgings is ensured by factors like corrosion resistance, proper heat treatment, precise manufacturing, adequate welding techniques, and protection against galvanic corrosion in marine and industrial environments.
Copper Nickel 90/10 Forgings are extensively utilized in marine and offshore settings due to their outstanding resistance to saltwater corrosion and biofouling. Typical applications include seawater piping, valve bodies, pump housings, flanges, and components for heat exchangers. In shipbuilding and naval vessels, they find use in fire mains, bilge and ballast systems, and engine cooling lines. In desalination plants and power generation facilities, these forgings are employed in condensers, evaporators, and cooling systems. Their thermal stability and non-sparking characteristics also make them ideal for chemical processing and oil refineries.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
