What makes our CuNi8 and CuNi14 strips special? They’re tailored for precision and durability. CuNi8, with its lower resistivity, is perfect for applications needing efficient conductivity, like heating cables or low-voltage resistors. CuNi14 steps it up with higher resistivity and thermal stability, making it a great fit for thermocouples and precision electrical components in demanding conditions. Their low temperature coefficients of resistance (TCRs of <57 and <30 x10⁻⁶/°C) ensure rock-steady performance, even when temperatures fluctuate, which is critical for maintaining accuracy in electrical systems.

These strips are corrosion-resistant, thriving in environments like industrial plants or marine settings where moisture or chemicals could degrade lesser materials. We produce them in thicknesses from 0.05mm to 5.0mm and widths up to 200mm, with custom options available to suit any project. Our hydrogen annealing process delivers a smooth, bright surface and a soft annealed condition, making them a breeze to work with during fabrication. Whether you’re crafting intricate resistors or robust thermocouples, our CuNi8 and CuNi14 strips are designed to make your job easier.
