CuNi Alloy The Ultimate Choice for High-Temperature and Corrosive Environments

Our CuNi alloy is a total rockstar, and we’re thrilled to show why it’s the ultimate choice for tackling high-temperature and corrosive environments. This copper-nickel alloy is built to deliver top-notch performance in some of the toughest conditions out there, from salty seas to chemical plants.

CuNi alloys, ranging from low-nickel grades like CuNi1 (~1% nickel) to high-nickel ones like CuNi44 (~44% nickel), are designed to handle temperatures up to 400°C with ease. Their corrosion resistance is next-level, especially in marine or acidic settings, thanks to a protective oxide layer that keeps rust at bay. Whether it’s CuNi10 for heating cables or CuNi44 for precision resistors, these alloys shine in harsh environments. With electrical resistivity between 0.10 and 0.49 µΩ·m, they offer stable performance for heating and electrical systems.

The thermal conductivity, ranging from 30 to 50 W/mK, makes CuNi awesome for quick, even heat distribution, perfect for applications like heat exchangers or low-power heating elements. With tensile strength of ~300-400 MPa, it’s durable enough for long-term use, and its high formability lets us craft it into wires, tubes, or flat strips for custom designs. Manufacturers love how easy it is to work with, whether for intricate components or heavy-duty setups.

The industry in 2025 is all about durability and sustainability, and our CuNi alloy is right on trend. There’s a huge demand for corrosion-resistant, cost-effective materials in marine, chemical, and renewable energy sectors. Being 100% recyclable, it’s a perfect fit for eco-friendly manufacturing. As compact, high-efficiency systems like offshore wind turbines or electric vehicle components keep trending, CuNi’s versatility and reliability make it a top pick.

Sure, Nichrome Cr20Ni80 can handle way higher temperatures, but CuNi’s lower cost and better corrosion resistance in wet environments make it unbeatable for moderate-heat applications. Stainless Steel 316 is tough but pricier and less conductive. Just keep CuNi away from extreme high-heat setups, though it thrives in most corrosive conditions like a pro.

From marine heat exchangers to precision heating systems, our CuNi alloy delivers the corrosion resistance, heat performance, and value that keep industries running strong in the toughest environments.
