China Top Manufacturer Nichrome Wire

Nichrome alloys are in the form of wire and strip for use at 1100℃~1250℃(2010°F~2280°F).It is supplied with bright and oxidized surface,spooled and coiled package.They are mainly used in industrial furnace and various heaters,resistors.    The advantages:Have higher hot and creep strength than FeCrAl alloys.Better ductility after long use than FeCrAl alloys.Generally have better corrosion resistance at room temperature than FeCrAl alloys.Longer life span than FeCrAl.Our Nichrome products are mailly included Ni80Cr20,Ni70Cr30,Ni60Cr15,Ni35Cr20,Ni30Cr20.Size rangeBright and white wire--0.025mm~3mmPickling wire:1.8mm~10mmOxidized wire:0.6mm~10mmFlat wire:thickness 0.05mm~1.0mm,width 0.5mm~5.0mmStrip:thickness 0.01mm~7.0mm,width 0.5mm~250mmOther sizes are available upon request.DatabasePropertes/GradeCr20Ni80Cr30Ni70Cr15Ni60Cr20Ni35Cr20Ni30Main Chemical  Composition(%)NiRestRest55.0-61.034.0-37.030.0-34.0Cr20.0-23.028.0-31.015.0-18.018.0-21.018.0-21.0Fe≤ 1.0≤ 1.0RestRestRestMax Continuous Service Temperature(℃)12001250115011001100Resistivity at 20℃(μ Ω · m)1.091.181.121.041.04Density(g/cm3)8.48.18.27.97.9Thermal Conductivity(KJ/m· h· ℃)60.345.245.243.843.8Coefficient of Thermal Expansion(α × 10-6/℃)1817171919Melting Point(℃)14001380139013901390Elongation(%)> 20> 20> 20> 20> 20Micrographic StructureausteniteausteniteausteniteausteniteausteniteMagnetic PropertyNon magneticNon magneticNon magneticNon magneticNon magneticStandardsNichrome alloy is supplied according to Chinese standard GB/T 1234-2012 and the other following standards shown below.ASTM(American Society for Testing and Materials):B344-01             DIN(Deutsche Industry Normen):DIN 17470-1984JIS(Japanese Industrial Standards):C2520-1999
