The CuNi14 34 Nickel Strip is a perfect blend of performance and practicality. Its nickel content (14-34%) gives it a unique edge: it’s more corrosion-resistant than lower-nickel alloys like CuNi10, yet more cost-effective than high-nickel alloys like CuNi44. Its thermal conductivity (30-45 W/mK) ensures efficient heat transfer, making it ideal for heat exchangers in desalination systems. With a tensile strength of 320-380 MPa, it’s tough enough to handle mechanical stress without compromising performance.

This alloy thrives in extreme environments, operating reliably from -50°C to 500°C. Its low temperature coefficient of resistance (TCR) ensures stable electrical properties, which is crucial for applications like sensors in desalination plants. Most importantly, its exceptional resistance to seawater and brine corrosion makes it a go-to material for marine and water treatment systems, where lesser materials would fail quickly.
