The CuNi34 Alloy Strip is a standout for its unique blend of properties. Its 34% nickel content gives it superior corrosion resistance compared to lower-nickel alloys like CuNi10 , making it a go-to for sensors exposed to saltwater, acids, or other aggressive chemicals. Compared to higher-nickel alloys like CuNi44, it’s more cost-effective without sacrificing performance. Its thermal conductivity (30 W/mK) ensures efficient heat dissipation, while its tensile strength (380 MPa) provides durability under mechanical stress.

This alloy’s low temperature coefficient of resistance (TCR) ensures stable electrical properties across a wide temperature range, from -100°C to 500°C. This makes it perfect for sensors in applications where temperature fluctuations are common, like marine monitoring systems or chemical processing plants. Its exceptional resistance to chemical corrosion also means it can handle the toughest environments, ensuring your sensors stay accurate and reliable for years.
