Copper-based Low Resistance Heating Alloy Wire CuNi44/NC050/2.0842/C72150 Promising Future Prospects

CuNi44 is a copper-nickel alloy with 44% nickel and 56% copper, known for its excellent electrical resistivity and thermal stability. It is widely used as a resistance alloy due to its consistent performance across a broad temperature range. The alloy offers exceptional resistance to oxidation and corrosion, even at elevated temperatures, making it reliable for harsh environments.

CuNi44 exhibits high mechanical strength, good ductility, and weldability, allowing it to be easily formed and fabricated into various components. Its low temperature coefficient of resistance ensures precise and stable electrical performance, making it ideal for precision resistors and temperature sensors.

Common applications include electrical heating elements, thermocouples, resistors, and components for measuring and control systems. Its corrosion resistance makes it suitable for marine and industrial applications. With its unique combination of electrical, thermal, and mechanical properties, CuNi44 is a versatile material for demanding industrial and electrical applications.
