Our CuNi44 wire is a total rockstar for precision resistance heating elements, built to deliver consistent performance in the toughest industrial and household applications. This copper-nickel alloy, with about 55% copper, 44% nickel, and traces of iron and manganese, is our go-to for situations where stable electrical resistance and durability are critical. Whether it’s heating elements for industrial furnaces, household appliances, or temperature control systems, this wire keeps things running smoothly.

What makes CuNi44 wire stand out is its high electrical resistivity (~0.49 µΩ·m) and excellent stability, which ensures precise heat output without fluctuations. It’s perfect for applications where you need reliable, controlled heating, like in electric ovens or lab equipment. Plus, it’s corrosion-resistant, shrugging off humid, acidic, or neutral environments, which means your heating elements last longer with less maintenance.

This wire’s versatility is a big win. It’s stable up to 600°C, which is plenty for most precision heating applications, and its oxidation resistance keeps it performing even in tough conditions. Its moderate electrical conductivity (~3-4% IACS) is great for fine-tuned resistance applications, and its good mechanical strength ensures it holds up under stress. From industrial kilns to home heaters, CuNi44 delivers.

We love how easy this wire is to work with. Its excellent formability makes it a breeze to coil, bend, or shape into whatever your heating element design needs—think tight coils or custom resistors. Need a specific diameter, resistance, or finish? We can tailor it to fit your specs, ensuring smooth manufacturing and keeping your project on track.
