Our CuNi1 NC003 low resistance heating wire is a total gem, and we’re thrilled to share why it’s a top pick for OEMs looking for efficient, budget-friendly heating solutions. This copper-nickel alloy, with just ~1% nickel, is designed to deliver reliable performance in low-heat applications, straight from our factory to your production line.

CuNi1 NC003 is all about efficiency, with an ultra-low electrical resistivity of ~0.10 µΩ·m, making it super conductive and perfect for heating systems where you want to keep power costs down. It’s stable up to 200°C, ideal for low-temperature setups like underfloor heating, heating cables, or small household appliances. Its corrosion resistance is killer, especially in wet or marine environments, thanks to a protective oxide layer that keeps it rust-free for years.

With a thermal conductivity of ~50 W/mK, this wire spreads heat quickly and evenly, ensuring consistent performance in heating elements. Its tensile strength (~300 MPa) keeps it durable, and the high formability means we can shape it into coils, flat wires, or custom designs to fit any OEM spec. Whether it’s for intricate heating pads or robust electrical connectors, this wire’s got the flexibility manufacturers need.

The industry in 2025 is buzzing with demand for cost-effective, sustainable materials, and our CuNi1 NC003 wire is right on trend. Sectors like consumer electronics, automotive, and marine are leaning hard into affordable, corrosion-resistant components for high-volume production. Being 100% recyclable, it’s a perfect fit for eco-friendly manufacturing goals. As low-power, compact heating systems keep trending in smart homes and EVs, this wire’s low resistance and high conductivity make it a go-to for OEMs.

Sure, Nichrome Cr20Ni80 can handle scorching temperatures, but CuNi1 NC003’s low cost and efficiency make it unbeatable for low-heat applications. CuNi44 Constantan is better for higher heat but pricier and less conductive. Just keep CuNi1 away from high-temperature environments, though it thrives in most wet conditions like a champ.

From floor heating to marine wiring, our CuNi1 NC003 low resistance heating wire delivers the efficiency, durability, and value that keep OEMs ahead of the game.
