Neil Metals stands out as a top-notch manufacturer and supplier of Copper Nickel 90/10 Forgings, proudly based in Kolkata, India. Known for their commitment to high-quality and precision-engineered products, the company serves both local and global markets. With a strong emphasis on customer satisfaction, Neil Metals guarantees that every forging adheres to strict industry standards and specifications. The Copper Nickel 90/10 alloy, celebrated for its remarkable corrosion resistance and durability, is expertly crafted into forgings using cutting-edge manufacturing techniques, making it perfect for challenging marine and industrial applications.
These Copper Nickel 90/10 Forgings consist of about 90% copper and 10% nickel, with a touch of iron and manganese added to boost strength and corrosion resistance. The alloy showcases impressive mechanical properties, boasting a tensile strength ranging from 275 to 350 MPa and a yield strength of around 130 MPa. It also offers great ductility, impact resistance, and outstanding weldability, even in seawater conditions. These characteristics make it an excellent choice for components that need to endure long service lives while resisting biofouling and high-pressure situations.

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.
Thanks to their exceptional resistance to seawater corrosion and biofouling, Copper Nickel 90/10 Forgings find applications across various industries. You’ll commonly see them in marine hardware, heat exchangers, condenser plates, pump components, and valve parts used in shipbuilding and offshore platforms. The alloy’s thermal conductivity and strength also make it a go-to for industrial piping systems and power plants. Plus, its resistance to stress corrosion cracking makes it ideal for chemical processing equipment, desalination plants, and other demanding environments where reliability and durability are a must.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
