NiCr resistance wire, commonly known as Nichrome wire, is a nickel-chromium resistance heating alloy widely used in electric heating applications. It provides stable electrical resistance together with good oxidation resistance, high-temperature mechanical properties, and formability.
Leader Steel offers NiCr resistance wire in grades including Cr20Ni80, Cr30Ni70, Cr15Ni60, Cr20Ni35, and Cr20Ni30. Among them, Cr20Ni80 is also commonly referred to as Ni80Cr20, Nichrome 80, or NiCr 80/20. Different NiCr grades can be selected according to resistance requirements, operating temperature, wire diameter, and heating element design.
FeCrAl resistance wire is an iron-chromium-aluminum resistance heating alloy featuring high electrical resistivity and good oxidation resistance at elevated temperatures. It is widely used for electric heating elements and industrial heating systems requiring reliable performance under high-temperature operating conditions.
Available FeCrAl wire grades include 0Cr27Al7Mo2, 0Cr24Al6RE, 0Cr21Al6Nb, 0Cr21Al6, 0Cr25Al5, 0Cr20Al6RE, 0Cr23Al5, 0Cr21Al4, 0Cr20Al3, 1Cr18Al3, 1Cr15Al5, 1Cr13Al4, and 1Cr12Al3. Different grades vary in alloy composition and performance, allowing selection based on operating temperature, electrical resistance, heating atmosphere, and service conditions.
Both NiCr and FeCrAl alloys are widely used as resistance heating materials, but their properties differ. Choosing between them depends on the required operating temperature, electrical resistance, heating environment, mechanical requirements, and element design.

Leader Steel supplies resistance heating wire in a range of diameters for different heating element designs and electrical resistance requirements.
| Product | Available Size |
|---|---|
| Resistance Heating Wire | Diameter 0.08–12 mm |
Wire diameter can be selected according to the required resistance value, current load, operating temperature, heating element dimensions, and application. Custom wire dimensions can also be discussed for specific resistance heating requirements.
NiCr and FeCrAl resistance wires are used to convert electrical energy into heat across a wide range of electric heating systems. Typical applications include:
Industrial electric furnaces
Heat-treatment furnaces
Electric heating coils
Industrial heating elements
Electric heaters
Tubular heating elements
Cartridge heating elements
Water heating equipment
Soldering and electrical heating tools
Household electrical heating appliances
Other high-temperature electric heating equipment
The appropriate alloy grade and wire diameter should be selected according to the operating temperature, required resistance, heating atmosphere, element structure, and expected service conditions.
Selecting the right resistance heating wire requires consideration of both the alloy grade and the operating conditions. Important factors include maximum operating temperature, electrical resistivity, wire diameter, heating atmosphere, element dimensions, mechanical requirements, and required resistance value.
NiCr resistance wire is commonly selected where stable resistance and good mechanical properties are important, while FeCrAl resistance wire is often considered for applications requiring high electrical resistivity and elevated operating temperatures.
If you are unsure which resistance wire grade is suitable for your heating element, provide your operating temperature, required resistance, wire diameter, heating environment, and application requirements. Leader Steel can help you select a suitable NiCr or FeCrAl resistance wire specification.
