Nichrome (also known as NiCr, nickel-chromium or chromium-nickel) is a family of alloys of nickel and chromium (and occasionally iron) commonly used as resistance wire, heating elements in devices like toasters, electrical kettles and space heaters, in some dental restorations (fillings) and in a few other applications.
2. High strength and ductility at the service temperatures
3. Low temperature coefficient of electric resistance to prevent changes in resistance at the
service temperature significantly from that attained to room temperature.
4. Excellent resistance to oxidation in air while moderate procedures
5. Suitable working and potential for being formed into the required shape.
Mainly for making heating elements. Household toasters, for instance, commonly employ thick nichrome wire in the construction of their heating elements, with this wire being wound into coils to achieve a specific electrical resistance. When an electrical current passes through, the nichrome wire heats up, emitting the desired heat for toasting. Notably, the oxidation resistance of nichrome prevents the heating element from succumbing to oxidation, ensuring longevity and reliability.
