Why is constantan used in wire?
Constantan is an alloy of copper and nickel. Thus, the resistivity of constantan changes very little with temperature thus, making the values of resistivity, fairly constant. This property is very helpful in making standard wire-wound resistances for using in electrical circuits.
Which has higher resistivity copper or constantan?
For example, the resistivity of manganin (which is an alloy of copper, manganese, and nickel) is about 25 times more than that of copper; and the resistivity of constantan (which is an alloy of copper and nickel)is about 30 times more than that of copper metal.

What is manganin and constantan?
The alloys manganin and constantan are used for making standard resistance coils as they have high resistivity, low-temperature coefficient of resistance, ability to attain good resistance values in small size. Their resistance value would change very little with temperature.
How do you calculate resistivity?
Resistivity, commonly symbolized by the Greek letter rho, ρ, is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l; ρ = RA/l. The unit of resistance is the ohm.
What is the diameter of a copper wire?
When copper wire is made, it is drawn through a series of dies which makes the wire thinner (and longer of course). In the American Wire Gauge (AWG), after passing through the first die it has a diameter of 7.34 mm (0.289 inches).
