Chuck Metals stands out as a top-notch manufacturer and supplier of high-performance copper alloys right in Singapore, Pulau Ujong. They specialize in precision-engineered Copper Nickel 70/30 Forgings, perfect for the tough demands of marine, offshore, and industrial settings. This alloy, known for its impressive strength, corrosion resistance, and longevity, is particularly suited for environments that face harsh seawater and high-pressure conditions. Chuck Metals offers a range of forged components, including flanges, rings, valve parts, and custom shapes, all crafted with tight tolerances and full traceability. With quick delivery, expert support, and a commitment to international standards, Chuck Metals has earned its reputation as a reliable partner for forged copper nickel solutions.
The Copper Nickel 70/30 Forgings are made up of about 70% copper and 30% nickel, with a touch of iron and manganese to boost their resistance to corrosion and erosion. This alloy boasts remarkable strength (with tensile strength ranging from ~380–550 MPa) and excels at resisting biofouling, pitting, and stress corrosion cracking in seawater. The forging process enhances the grain structure, toughness, and fatigue strength, making these components perfect for high-pressure and high-vibration systems. Plus, Copper Nickel 70/30 maintains good thermal conductivity and weldability, striking a great balance between mechanical strength and corrosion resistance for critical applications.

You’ll find Copper Nickel 70/30 Forgings widely used in marine hardware, seawater piping systems, heat exchanger components, valve bodies, pump parts, and condenser fittings. In naval and offshore structures, they’re utilized in risers, manifolds, and cooling systems, thanks to their durability and resistance to saltwater corrosion and marine life. Power plants and desalination facilities rely on them for brine and cooling water circulation systems. Their strength, long-lasting corrosion resistance, and compatibility with welding and forming make them the go-to choice for forged parts in systems that operate under high pressure, flow, 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.
