NiCr 60/15 80/20 90/10 8020 Nichrome 19X0.574 18×0.523+1×0.574 Pure 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,
