Our CuNi1 wire is a rockstar in low-voltage circuit breakers, where its low resistivity ensures efficient power flow without overheating. It’s also a favorite in thermal overload relays, protecting equipment by sensing temperature spikes. Beyond that, you’ll find it in electric blankets, heating mats, and even some automotive wiring systems where reliability is critical. Its corrosion resistance makes it a solid pick for environments exposed to moisture or chemicals, ensuring longevity in tough conditions.
Why Our CuNi1 Wire Stands Out
Compared to others in the market, our CuNi1 wire offers unmatched consistency in resistance, which is critical for precise circuit breaker performance. We’ve fine-tuned our manufacturing to deliver wires with uniform resistivity and superior stability, reducing the risk of failures in your systems. Our wire’s ductility makes it a breeze to fabricate, saving you time and costs during production. Plus, we offer it in a range of sizes—0.1mm to 10mm for round wires and custom dimensions for ribbons and strips—to fit your exact needs. We also prioritize quick lead times and competitive pricing, ensuring you get top-quality wire without breaking the bank.
