Corrosion-Resistant CuNi Wire for Reliable Performance
Our CuNi wire is the kind of material you can count on when things get tough. This copper-nickel alloy is engineered to resist corrosion like a champ, making it a top choice for projects where reliability is non-negotiable. Whether it’s battling saltwater or powering precision electronics, our CuNi wire gets the job done.
Corrosion resistance is where this wire really shines. The nickel content—ranging from 10% in CuNi10 to 44% in CuNi44—teams up with additives like iron to fend off rust and degradation, even in brutal environments like marine or chemical plants. It’s why you’ll find our wire in ship wiring, offshore rigs, and desalination systems, holding strong where other materials would crumble.
But it’s not just about fighting corrosion. CuNi wire delivers rock-solid electrical performance, with consistent resistivity that’s perfect for resistors, thermocouples, and other precision components. It’s a favorite in electronics and aerospace because it doesn’t skip a beat, even under stress. Plus, it can handle heat like a pro, staying stable up to 400°C, or even 500°C for certain grades, so it’s great for industrial heating systems.
We love how easy this wire is to work with. It’s super workable, meaning you can bend, weld, or shape it without breaking a sweat. Need it in a specific form, like a ribbon or strip? Or a particular nickel blend? We can customize it to fit your needs, making it a versatile pick for everything from energy projects to communication cables.
The industry’s moving toward materials that are both high-performing and sustainable, and CuNi wire fits right in. It’s recyclable, which is a win for eco-friendly initiatives, and its long lifespan means less waste and fewer replacements. As marine and energy sectors demand tougher, longer-lasting solutions, CuNi wire is stepping up as a go-to material.
Compared to other options, CuNi wire has a unique edge. Pure copper’s great for conductivity but falls apart in corrosive settings. Stainless steel’s tough but lacks the electrical properties needed for many applications. Cu-Sn alloys are solid, but CuNi often outperforms them in marine environments and precision tasks.
We produce our CuNi wire to meet rigorous standards like ISO 9001, so you know you’re getting quality you can trust. Whether you’re wiring a ship or building cutting-edge electronics, our wire’s ready to deliver reliable performance. Got a specific requirement? Let us know, and we’ll tailor it for you.
