New Hot Customized CuNi Alloy Round Ribbon & Wire For Sale

Our customized low resistance CuNi alloy wire is a total standout for thermal circuit breakers, and we’re stoked to show off why it’s such a game-changer. This copper-nickel alloy is designed to deliver precision, reliability, and efficiency, tailored to meet the exact needs of circuit breaker manufacturers.

CuNi alloys, with nickel content ranging from 1% to 44% (like CuNi1 to CuNi44), are built to handle temperatures up to 400°C, making them perfect for the heat demands of thermal circuit breakers. Their corrosion resistance is top-notch, shrugging off rust in humid or marine environments with a protective oxide layer—ideal for breakers exposed to tough conditions. The low electrical resistivity, between 0.10 and 0.49 µΩ·m, ensures efficient current flow, minimizing energy loss and keeping breakers responsive.

With thermal conductivity of 30-50 W/mK, this wire transfers heat quickly and evenly, crucial for breakers that rely on precise thermal triggers. Its tensile strength (~300-400 MPa) makes it durable for long-term use, and the high formability lets us customize it into fine wires, coils, or unique shapes to match any breaker design. Whether you need a specific diameter, resistance, or configuration, we’ve got you covered with OEM-level precision.

The industry in 2025 is all about smart, sustainable solutions, and our CuNi wire is right on trend. There’s a growing demand for reliable, corrosion-resistant materials in electronics, automotive, and renewable energy sectors, especially for circuit protection in EVs or solar systems. Being 100% recyclable, it’s a great fit for eco-friendly manufacturing. As compact, high-efficiency circuit breakers keep trending, CuNi’s low resistance and customizability make it a top pick for cutting-edge designs.

Sure, Nichrome Cr20Ni80 can handle higher temperatures, but our CuNi wire’s lower cost and corrosion resistance make it ideal for moderate-heat circuit breaker applications. CuNi44 Constantan is similar but pricier with higher resistivity, which can affect efficiency. Just keep CuNi away from extreme high-heat environments, though it thrives in most conditions like a pro.

From automotive circuit breakers to industrial controls, our customized low resistance CuNi alloy wire delivers the precision, durability, and efficiency that keep manufacturers ahead of the curve.
