Copper is great, but adding 10% nickel makes our CuNi10 wire a cut above. The nickel boosts corrosion resistance and strength, making it tougher than pure copper while maintaining excellent conductivity. Compared to stainless steel, our wire offers better electrical resistivity for heating applications and superior corrosion resistance in marine or chemical environments. While pure copper is cheaper and more conductive, it corrodes easily, whereas our CuNi10 wire delivers long-term reliability.

Customization is our strength. Need a fine wire for a compact heating cable? We’ve got it covered. Want a specific length for an industrial resistor? No problem. Our advanced manufacturing techniques, like precision wire drawing and alloy processing, ensure tight tolerances that meet the strictest industry standards.
