What makes our CuNi1, CuNi2, and CuNi8 strips stand out? They’re tailored for efficiency and durability. CuNi1, with its ultra-low resistivity, is perfect for high-conductivity applications like heating cables. CuNi2 offers a slight step-up in resistivity for more demanding low-voltage components. CuNi8, with 8% nickel, provides a balanced option for precision resistors and thermocouples. Their low temperature coefficients of resistance (TCRs ranging from <57 to <100 x10⁻⁶/°C) ensure stable performance, even when temperatures fluctuate, which is critical for heating cables and electrical components.

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 heating cables or precision resistors, our CuNi1, CuNi2, and CuNi8 strips are designed to make your job easier.
