Chuck Metals is a well-respected manufacturer and supplier of specialty copper alloys based in Singapore, Pulau Ujong. They provide high-quality Copper Nickel 95/5 Bars and Rods, perfect for marine, industrial, and plumbing applications. These products are celebrated for their exceptional corrosion resistance and workability, making them a great fit for environments that encounter fresh or slightly saline water. Chuck Metals prides itself on maintaining strict quality control, ensuring precise dimensions, and delivering reliably to both local and international markets. With competitive pricing and attentive customer support, they have become the go-to choice for Copper Nickel 95/5 products tailored to meet specific performance and fabrication needs.
The Copper Nickel 95/5 Bars and Rods consist of about 95% copper and 5% nickel, with small amounts of iron and manganese added to boost their mechanical properties and corrosion resistance. This alloy boasts impressive strength (with a tensile strength ranging from 250 to 350 MPa), excellent ductility, and outstanding resistance to dezincification and biofouling. While it may not be as corrosion-resistant in seawater as some higher-nickel grades, it performs admirably in freshwater and mildly brackish conditions. The rods and bars are easy to machine, weld, and shape, making them ideal for components that require moderate strength and durable corrosion protection.

You’ll often find Copper Nickel 95/5 Bars and Rods in plumbing fittings, water supply systems, cooling circuits, and condenser components in freshwater settings. In marine environments, they’re suitable for non-critical parts that are exposed to slightly brackish water. This alloy is also utilized in fire suppression systems, HVAC components, and low-pressure piping where resistance to mineral-rich or corrosive water is essential. Thanks to its antimicrobial properties, it’s a great choice for potable water applications. With its excellent formability and corrosion resistance, Copper Nickel 95/5 is perfect for cost-effective, long-lasting performance in mild service conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
