Corrosion resistance is another big win. The high nickel content makes this strip a beast against rust, whether it’s in humid factories, chemical plants, or even marine environments. It keeps performing where other materials would corrode, which means less maintenance and longer-lasting components. That’s a huge plus for industries where reliability is everything.
We love how easy CuNi44 strip is to work with. Its excellent formability lets you cut, shape, or weld it into whatever your design calls for—thin strips for resistors or custom shapes for components. Need a specific thickness or width? We can customize it to match your project’s exact needs, making production a breeze.
The industry’s all about materials that are precise, durable, and sustainable, and CuNi44 strip checks every box. It’s recyclable, which is awesome for eco-friendly projects, and its long lifespan means fewer replacements and less waste. With electronics and smart manufacturing on the rise—think IoT devices and automated systems—CuNi44’s precision and reliability are in high demand. It’s also a great fit for the push toward energy-efficient technologies.
Compared to other materials, CuNi44 shines. Pure copper’s a conductivity champ but fails in corrosive or high-heat settings. CuNi20 offers better conductivity but less corrosion resistance and thermal stability, making CuNi44 the go-to for precision resistors. Nichrome’s great for heating but lacks the electrical precision and corrosion resistance of CuNi44. This strip hits the sweet spot for high-performance applications.
