Our CuNi10 bar is a rock-solid choice for marine components that need to stand up to the toughest saltwater environments. This copper-nickel alloy, with 10% nickel and often a bit of iron (CuNi10Fe), is engineered for corrosion resistance and durability, making it a favorite for marine and coastal projects.

What sets CuNi10 bar apart is its ability to laugh off seawater corrosion. It’s perfect for ship fittings, valves, piping, and heat exchangers in marine applications like shipbuilding, offshore platforms, and desalination plants. The iron in CuNi10Fe gives it an extra edge against rust, so your components keep performing even in the saltiest conditions. It’s also got decent electrical conductivity—around 20% IACS—making it useful for marine electrical systems where reliability is key.

This bar is super easy to work with. Its excellent formability means you can machine, weld, or shape it into whatever your project demands. Whether you need custom-sized bars or specific profiles for a marine fitting, we can tailor it to fit your specs, saving you time and effort during production. Plus, it’s stable up to 400°C, so it handles the heat in marine heat exchangers or low-temperature systems without breaking a sweat.

The industry’s moving toward materials that are both high-performing and sustainable, and CuNi10 bar fits the bill. It’s fully recyclable, which is great for eco-friendly initiatives, and its long lifespan means fewer replacements and less waste. With marine industries expanding—think offshore wind farms and global shipping—demand for corrosion-resistant materials like CuNi10 is skyrocketing. Energy efficiency is also a big trend, and CuNi10’s reliability in heat exchangers supports greener marine systems.

Compared to other materials, CuNi10 bar holds its own. Pure copper’s a conductivity king but corrodes fast in seawater. CuNi30Mn offers better thermal stability and corrosion resistance but at a higher cost and lower conductivity, making CuNi10 a sweet spot for marine applications. Stainless steel’s tough but doesn’t match CuNi10’s seawater resistance or electrical properties. This bar is the go-to for marine durability.

We produce our CuNi10 bar to meet strict standards like ISO 9001, ensuring you get consistent quality every time. Whether you’re building ship components or coastal infrastructure, this bar’s ready to deliver. Need a specific size or shape? Let us know, and we’ll make it happen.
