What makes our NC030 CuNi23 wire special? It’s the perfect mix of precision and resilience. Its low temperature coefficient of resistance (TCR) of less than 16 x10⁻⁶/°C ensures stable electrical performance, even when temperatures swing. This is a big deal for industrial resistors and fuses, where consistency is key to preventing system failures. Plus, its corrosion resistance makes it ideal for environments where moisture, chemicals, or saltwater could degrade lesser materials.

We produce this wire in a range of sizes to fit any project—wires from 0.05mm to 8mm in diameter, ribbons as thin as 0.05mm, and strips up to 200mm wide. Our hydrogen annealing process gives it a smooth, bright surface and a soft annealed condition, making it a breeze to work with during fabrication. Whether you’re crafting intricate resistors or robust fuses, our NC030 CuNi23 wire is designed to streamline your manufacturing process while delivering top-notch performance.
