Our CuNi alloy is a total superstar, and we’re pumped to share why it’s the optimal choice for applications needing killer corrosion resistance and long-term performance. This copper-nickel alloy is built to last, delivering reliability and efficiency in some of the toughest environments out there.

CuNi alloys, with nickel content ranging from 1% (like CuNi1) to 44% (like CuNi44), are champs at fighting corrosion, especially in marine, chemical, or humid settings. A protective oxide layer keeps rust and degradation at bay, making it a go-to for things like shipboard wiring or heat exchangers. They’re stable up to 400°C, perfect for moderate-heat applications, and their electrical resistivity (0.10-0.49 µΩ·m) stays rock-steady, ensuring consistent performance in resistors, sensors, or heating elements.

The thermal conductivity, between 30-50 W/mK, is a big win, allowing quick and even heat distribution, which is awesome for systems needing efficient thermal management. With a tensile strength of ~300-400 MPa, these alloys are tough enough for long-term use without wearing out. Plus, their formability is top-notch—we can shape them into wires, flat strips, or tubes for all kinds of custom designs, from precision electronics to heavy-duty industrial components.

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

Sure, Nichrome Cr20Ni80 can handle much higher temperatures, but CuNi’s corrosion resistance in wet environments and lower cost make it ideal for moderate-heat applications. Stainless Steel 304 is durable but less conductive and more prone to corrosion in saltwater. Just keep CuNi away from extreme high-heat setups, though it thrives in most corrosive conditions like a pro.

From marine wiring to precision sensors, our CuNi alloy delivers the corrosion resistance, longevity, and performance that keep industries running strong and reliable for the long haul.
