Special resistor materials: nichrome, Physics

Nichrome: Nichrome is an alloy of Manganese 1.5%, nickel 75% to 78%, chromium 20% to 23% and a little percentage of iron.

Properties:

1.      Its electrical resistivity is 100*10-8 ohm-m.

2.      The maximum permissible working temperature is 11000C.

3.      It is ductile and can be drawn into wires or any other form.

4.      It is mechanically strong.

Uses: It is used in making heating elements for electric irons, electric ovens, room heaters, electric furnaces etc. it is also used for manufacturing of wire wound resistors.
