Our CuNi alloy wire is flying off the shelves, and we’re pumped to share why it’s the perfect choice for electrical heating cables. This copper-nickel alloy is all about delivering efficient, reliable heat while keeping costs down, making it a hot pick for manufacturers and installers alike.

CuNi alloys, with nickel content ranging from 1% to 44% (like CuNi1 to CuNi44), are built to handle temperatures up to 400°C, ideal for heating cables in underfloor systems, industrial heaters, or even marine applications. Its corrosion resistance is top-notch, shrugging off rust in humid or salty environments thanks to a protective oxide layer—perfect for cables exposed to tough conditions. The electrical resistivity, between 0.10 and 0.49 µΩ·m, ensures efficient power delivery, saving energy while keeping things toasty.

With thermal conductivity of 30-50 W/mK, this wire spreads heat fast and evenly, so your heating cables perform consistently without hot spots. Its tensile strength (~300-400 MPa) keeps it durable for long-term use, and the high formability means we can craft it into tight coils or custom shapes to fit any cable design. Whether it’s for thin, flexible cables or thicker, heavy-duty ones, this wire’s got you covered.

The industry in 2025 is all about efficiency and sustainability, and our CuNi wire is right on trend. There’s a massive demand for cost-effective, corrosion-resistant materials in smart homes, automotive, and renewable energy sectors, like electric vehicle heating systems or solar panel cables. Being 100% recyclable, it’s a solid fit for eco-friendly manufacturing. As low-power, high-efficiency heating solutions keep trending, CuNi’s low resistance and high conductivity make it a favorite for cutting-edge designs.

Sure, Nichrome Cr20Ni80 can handle way higher temperatures, but our CuNi wire’s affordability and corrosion resistance make it the go-to for moderate-heat applications. CuNi44 Constantan is similar but pricier with higher resistivity. Just keep CuNi away from extreme high-heat setups, though it thrives in most environments like a pro.

From underfloor heating to industrial cables, our hot sale CuNi alloy wire delivers the efficiency, durability, and value that keep heating systems running strong and customers happy.
