Our 23% nickel copper nickel alloy wire, with a diameter range of 0.1 to 10mm and 30-45% elongation, is a total rockstar for industries needing durability and flexibility. This CuNi alloy is designed to shine in tough conditions, and we’re pumped to show off what it can do.

With ~23% nickel and the rest copper, this alloy handles temperatures up to 350°C like a pro, making it perfect for moderate-heat applications like heating cables or electrical connectors. Its corrosion resistance is killer, especially in marine or humid environments, thanks to a protective oxide layer that keeps rust at bay. The 30-45% elongation is a big deal—it lets us bend, twist, or coil the wire without it snapping, which is awesome for intricate designs or dynamic systems.

The electrical resistivity, around 0.30 µΩ·m, is super stable, ensuring consistent performance in low-power heating elements or precision resistors. Its thermal conductivity (~35 W/mK) means it spreads heat quickly and evenly, great for applications needing efficient thermal management. The diameter range—0.1mm for ultra-fine work to 10mm for heavier-duty tasks—gives manufacturers tons of options, whether they’re crafting tiny sensors or robust marine wiring.

The industry in 2025 is all about sustainability and versatility, and our CuNi wire is right on trend. There’s a huge demand for corrosion-resistant, flexible materials in marine, automotive, and renewable energy sectors. Being 100% recyclable, it’s a perfect fit for eco-friendly manufacturing. As compact, efficient systems like electric vehicle components or offshore wind turbines keep trending, this wire’s formability and moderate cost make it a go-to for reliable designs.

Sure, Nichrome Cr20Ni80 can handle way higher temperatures, but our 23% nickel CuNi wire’s corrosion resistance and lower resistivity make it ideal for moderate-heat, wet environments. CuNi44 Constantan has slightly better heat resistance but is pricier and less flexible. Just keep this CuNi wire away from extreme high-heat setups, though it thrives in most corrosive conditions like a champ.

From marine electrical systems to precision heating elements, our 23% nickel CuNi alloy wire delivers the corrosion resistance, flexibility, and performance that keep industries running strong and efficient.
