Stranded Resistance Heating Wire
Stranded resistance heating wire is made of Nichrome alloys, such as Ni80Cr20, Ni60Cr15, etc. It can be made with 7 strands, 19 strands, or 37 strands, or other configurations. Smooth bunch configurations with tight lays are produced with Ni80Cr20, Ni60Cr15 or other alloys.
Stranded resistance heating wire has many advantages, such as deformation ability, thermal stability, mechanical character, shockproof ability in thermal state and anti-oxidization. For heating,
resistance Wire mesh must be stable in air when hot. 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 mesh from breaking or burning out. Due to Nichrome Wire'srelatively 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:
