NCHW Stranded Wire

Model NO.: NCHW1 Material: Nichrome Process Method: Stranded Solid Nichrome Wire Specification: RoHS, ISO 9001: 2008 HS Code: 7505220000 Product Type: Wire Carbon Content: Low Carbon Trademark: TANKII Origin: China NCHW Stranded Wire
 
Stranded Resistance Wire is made of Nichrome Alloys, such as NCHW1, NCHW2, etc. It 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. Material 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,
Typical stranded resistance alloys and constructions are:

Alloy	Standard Strand Construction, mm	Resistance,Ω/m	Strand Diameter Nominal, mm	Meter per Kilo
