Features of Nickel Chromium Electric Resistance Wire and Ribbon
(Features of Nichrome wire, ribbon)

This is the material of JIS C2520 - 1999, Nickel Chromium Electric Heating Wire Class 1, Class 2
(Nichrome Heating Wire Class 1, Class 2).

1. Comparison of copper-nickel resistance wire CN49W and manganin precision resistance
   wire CMW reveals that the volume resistivity of the former is approximately 2 times greater,
   the tensile strength is approximately 1.5 times greater, and the corrosion resistance and
   the heat resistance is at a high level as well.
2. Due to the above features, CN49W is widely used as a general electric resistance material.
