`
`Nichrome Alloy Properties and Uses in Industry | Union City Filament
`
`ABOUT NICHROME ALLOYS
`
`Patented in 1905, Nichrome is the oldest air-stable resistance-heating alloy (that is
`documented). Nichrome alloys consist of nickel, chromium, iron, and sometimes other
`elements. The Nichrome we use here at Union City Filament is an austenitic alloy that has
`the highest nickel content. This high-resistance material is typically used in applications
`that have a maximum operating temperature of up to 1,250°C (2,280°F).
`
`PROPERTIES OF NICHROME WIRES
`
`Nichrome alloys are known for their high mechanical strength, as well as their high creep
`strength. Learn some of the bene ts of using this material below.
`·
`DUCTILITY AFTER USE
`
`Nichrome is known for remaining ductile, even after long usage.
`·
`HIGHER HOT AND CREEP STRENGTH
`
`Compared to other air-stable resistance alloys, Nichrome alloys have a higher hot and
`creep strength.
`·
`HIGHER EMISSIVITY
`
`When fully oxidized, Nichrome alloys have a higher emissivity compared to other air-
`stable resistance alloys. This means that at the same surface load, the element
`temperature of Nichrome is lower than other alloys.
`·
`NON-MAGNETIC
`
`In some low-temperature applications, a non-magnetic material is preferred. Nichrome is
`non-magnetic, making it the preferred choice over other air-stable resistance alloys,
`which are only non-magnetic above 600°C (1100°F).

`Nichrome Alloy Properties and Uses in Industry | Union City Filament
`While there are some exceptions (such as atmospheres containing sulphur and certain
`controlled atmospheres), Nichrome alloys typically have a better corrosion resistance at
`room temperature compared to non-oxidized air-stable resistance alloys.
`
`
`APPLICATIONS FOR NICHROME ALLOYS
`
`While almost any conductive wire can be used for heating, most metals conduct
`electricity with great e ciency. This requires the metals to be formed into thin, delicate
`wires, so there is enough resistance to generate heat. When most metals are heated,
`they oxidize quickly, which makes them brittle and break when heated in air. Nichrome
`wire, however, develops an outer layer of chromium oxide, which makes the wire
`thermodynamically stable in air, mostly impervious to oxygen, and protects the heating
`element from further oxidation.
`
`With its high-temperature strength and good workability, Nichrome is an ideal material
`to use for demanding applications in the electric appliance industry, such as hair dryers
`and heat guns. It is also commonly used in electronic cigarettes (e-cigarettes) and other
`vaping (vape) applications.
`
`Some other common applications for Nichrome alloys include: ironing machines, water
`heaters, soldering irons, metal sheathed tubular elements, cartridge elements, quartz
`tube heaters, infrared emitters and other precision heating element (heater)
`applications.
