What is the grade of Copper-nickel resistance wire? What are its applications?

Copper-nickel resistance wire is an alloy material commonly used in resistor manufacturing and has excellent resistance properties and stability. The following are some common copper-nickel resistance wire grades:

Manganin (Mangan copper-nickel resistance wire): Manganin is a copper-nickel resistance wire containing manganese. It has a low temperature coefficient and a high temperature coefficient of resistance, and is suitable for the manufacture of high-precision resistors.

Constantan: Constantan is a copper-nickel resistance wire with stable resistance characteristics and low temperature coefficient. It is widely used in electronic equipment, measuring instruments and resistor manufacturing.
