Nickel Chrome Stranded Wire for Electric Heater
Stranded resistance wire is made of Nichrome alloys, such as
Nichrome 80/20,Nichrome 60/16, etc.
Stranded nichrome wire can be made with 7 strands, 19 strands, or 37 strands, or other
configurations.
Stranded resistance heating wire has many advantages, such as
deformation ability, thermal stability, mechanical character,
shockproof ability in thermal state and anti-oxidization.
Nichrome Wire forms a protective layer of chromium oxide when it is heated for
the first time.
Nichrome wire beneath the layer will not oxidize, preventing the wire from
breaking or burning out.
Due to Nichrome Wire's relatively high resistivity and resistance
to oxidation at high temperatures, it is widely used in heating
elements, electric furnace heating and heat-treating processes in
the chemical, mechanical, metallurgical and defense industries,
