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.
