Hot Sale CuNi1 Resistance Wire (NC003) - Customizable Heat-Resistant CuNi Wires at Competitive Prices

Manganin alloy is a specialized electrical resistance alloy composed mainly of copper, manganese, and nickel. It offers a low resistance temperature coefficient, minimal thermal EMF relative to copper, excellent long-term stability, and superior weldability and workability. These properties make it ideal for high-precision instruments for measuring voltage, current, resistance, and more. Manganin also serves as a reliable heating wire for low-temperature applications, such as air-conditioning systems and household heating devices.

Detailed Photos

CuNi wire, or copper-nickel alloy wire, is valued for its strong corrosion resistance, stable resistivity, and durability. Made primarily from copper and nickel, it performs well in marine environments, chemical processing, and electrical devices. With high thermal stability, CuNi wire is ideal for precision instruments, resistance measurement, and heating elements in systems like air conditioning and household heaters. It's also easy to weld and shape, making it suitable for use in aerospace, automotive, and energy sectors. Available in various alloy ratios (like CuNi10, CuNi30, and CuNi40), CuNi wire offers flexibility for a wide range of applications.

 

 

CuNi wire can be precisely customized to meet specific requirements, with the surface color of the wire varying based on the copper and nickel content. Higher copper content typically gives the wire a warmer, reddish hue, while a higher nickel concentration results in a cooler, silver-grey appearance.

This customization in composition allows CuNi wire to be tailored not only in terms of performance-such as corrosion resistance and conductivity-but also in aesthetic qualities, providing a suitable solution for applications requiring specific visual and functional characteristics.
