Versatile CuNi Resistance Wire for Custom Engineering Solutions
Our CuNi resistance wire is like the Swiss Army knife of alloys—versatile, reliable, and ready to tackle your toughest engineering challenges. This copper-nickel alloy is our pride and joy for custom projects, offering the flexibility and performance you need to bring your ideas to life.
What makes this wire so special is how customizable it is. Whether you need a specific resistivity for a precision resistor or a unique shape for a complex component, we can dial in the nickel content—think CuNi10 to CuNi44—or deliver it as wire, strip, or ribbon. It’s a dream for engineers working on bespoke solutions in electronics, automotive, or even aerospace.
Corrosion resistance is another feather in its cap. With nickel and additives like iron, this wire shrugs off saltwater, chemicals, and humidity. That’s why it’s a staple in marine engineering, from ship wiring to offshore sensors, where other materials would rust out fast. It’s built to keep performing, no matter the environment.
For applications like heating elements or thermocouples, CuNi wire’s got you covered. It’s stable up to 400°C, with some grades pushing 500°C, and its consistent electrical resistivity makes it perfect for precise control in resistors or temperature sensors. Plus, it’s super easy to work with—bend it, weld it, shape it without a hassle, which saves serious time in manufacturing.
The industry’s all about materials that can do more while being sustainable, and CuNi resistance wire fits the bill. It’s recyclable, which is awesome for eco-friendly projects, and its long lifespan means fewer replacements, less waste, and lower costs over time. As custom engineering and IoT solutions boom, CuNi’s versatility is in high demand.

Compared to other materials, CuNi stands tall. Pure copper’s a conductivity king but flops in harsh conditions. Nichrome’s great for high-heat applications but less flexible for precision work. Cu-Sn alloys are solid but don’t match CuNi’s customization potential or marine-grade corrosion resistance.
We craft our CuNi resistance wire to meet top standards like ISO 9001, so you’re getting quality you can bank on. Whether you’re designing cutting-edge electronics or rugged marine systems, this wire’s ready to make your project pop. Got a specific vision? Let us know, and we’ll tailor it to perfection.
