Nichrome wire is made of a non-magnetic alloy composed primarily of nickel, chromium, and iron. Nichrome is characterized by its high resistivity and good oxidation resistance. Nichrome wire also has good ductility after use and excellent weldability.
The number that comes after the Nichrome wire type indicates the percentage of nickel in the alloy. For example, "Nichrome 60" has approximately 60% Nickel in its composition.
FOR STRESS RELIEVING APPLICATION, generally for resistive heating the below given wire lengths are used to make coils, for 230 V AC @ 45 Amps
