Nichrome wire is a high temperature resistance belt that fits best in the applications that are conducted at the elevated temperatures. It creates the oxide layer when heated to prevent the further corrosion of alloy such that it avoids the breakages or burns. It is an excellent anti-corrosion alloy that exhibits large coefficient of electric resistance and high tensile strength. The wire produces large amount of heat when it is heated abruptly.
The excellent resistance to corrosion and high electric resistivity at the elevated temperature limits make Nichrome wire purposeful in the production of heating appliances such as electric furnace, chemical houses, machines and metallurgy.
