What makes our CuNi6 and CuNi8 strips special? They’re tailored for precision and reliability. CuNi6, with its lower resistivity, is perfect for applications needing high conductivity, like heating cables or low-voltage resistors. CuNi8 steps it up with slightly higher resistivity, making it a great fit for more demanding precision resistors and thermocouples. Their low temperature coefficients of resistance (TCRs of <60 and <57 x10⁻⁶/°C) ensure stable performance, even when temperatures fluctuate, which is critical for precision resistors.
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 CuNi6 and CuNi8 strips are designed to make your job easier.
