Our CuNi 23% alloy wire, with a thermal expansion of 50 x10^-6/°C and a super low 0.12 µΩ·m resistivity, is a total standout for industries needing precision and reliability. This copper-nickel wire is crafted to deliver awesome performance in tough environments, and we’re stoked to share what it’s all about.

With ~23% nickel and the rest copper, this alloy is built to handle temperatures up to 350°C, making it perfect for moderate-heat setups like electrical connectors, heating cables, or precision sensors. Its corrosion resistance is killer, especially in marine or humid environments, where a protective oxide layer keeps rust at bay. The low resistivity of 0.12 µΩ·m means it conducts electricity super efficiently, saving power in applications like low-power resistors or wiring systems.

The thermal expansion of 50 x10^-6/°C is a big deal—it keeps the wire’s dimensions stable even as temperatures shift, which is crucial for precision components that can’t afford to warp. With a tensile strength of ~350 MPa and thermal conductivity of ~35 W/mK, it’s durable and spreads heat evenly, making it great for systems needing quick thermal response. Plus, its high formability lets us shape it into fine wires or custom designs, perfect for everything from tiny sensors to robust marine applications.

The industry in 2025 is all about efficiency and sustainability, and our CuNi 23% wire is right on trend. There’s a huge demand for corrosion-resistant, cost-effective materials in marine, automotive, and renewable energy sectors, like offshore wind or electric vehicle systems. Being 100% recyclable, it’s a solid fit for eco-friendly manufacturing. As precision electronics and compact devices keep trending, this wire’s low resistivity and stable thermal expansion make it a top choice for reliable, high-volume production.

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

From marine wiring to precision sensors, our CuNi 23% alloy wire delivers the corrosion resistance, stability, and efficiency that keep industries running smooth and strong.
