WebNichrome Wire NiCr8020 Flat Wire for Industrial Furnace Heating Elements Nickel Chromium Alloy Introduction: Nickel Chromium alloy has high resistivity, good anti-oxidation properties, high temperature strength, very good form stability and weld ability. It is widely used in electrical heating element material, resistor, industrial furnaces, etc. … WebElectrical resistivity as a function of chromium content for nickel-chromium alloys: The addition of the appropriate reactive alloying elements will affect the properties of the scale. The operating conditions of the alloy will largely influence the composition that should be used. ... This combination is called chromel-alumel, and similar to ...
WebNichrome, a non- magnetic 80/20 alloy of nickel and chromium, is the most common resistance wire for heating purposes because it has a high resistivity and resistance to oxidation at high temperatures. When used as a heating element, resistance wire is usually wound into coils. WebChromel–alumel thermocouples are used for temperatures below 1000°C, platinum–platinum–rhodium thermocouples are used for temperatures below 1300°C, and tungsten–rhenium alloy thermocouples are used for temperatures below 2200°C.
