Kanthal BGH SHUQING Quality Nickel-Chrome-Fe Heating Wire Use For Heating Element

Code: Cr20Ni80、Cr15Ni60、Cr20Ni35、Cr20Ni30Material: Nickel-Chrome, Nickel-Chrome-Fe wireSpecifications: φ0.035mm~φ9.0mmfeatures: nickel-chromium, nickel, ferrochrome alloy wire with electric high temperature oxidation resistance, high strength, not soften and a series of advantages. When used in a long time, the same type and the permanent elongation is very small, which is more Cr20Ni80 alloy with excellent comprehensive properties, is to produce high-quality varieties of choice for electric components. The products are widely used in industrial furnace, metallurgy, machinery, household appliances and other industries producing heating elements and resistance elementsProduct specifications:Cold drawn alloy wireDia.φ1.0-φ9.0mmBright wireDia.φ0.035-φ1.0mmTechnical parameters of Nickel-chrome,Nickel-chrome-Fe wire Table:Performance materialCr20Ni80Cr30Ni70Cr15Ni60Cr20Ni35Cr20Ni30CompositionNiRestRest55.0～61.034.0～37.030.0～34.0Cr20.0～23.028.0～31.015.0～18.018.0～21.018.0～21.0Fe≤1.0≤1.0RestRestRestMaximum temperature℃12001250115011001100Meltiing point ℃14001380139013901390Density g/cm38.408.108.207.907.90Resistivity
