FeCrAl alloy is made from a high temperature ferritic iron-chromium-aluminum alloy that can be used at temperatures up to 1350 degrees. Typical applications for 0Cr21Al6Nb are electrical heating elements in high temperature furnaces in heat treatment, ceramics, glass, steel and electronics.
FeCrAl heating wire Features and advantages
1. High using temperature, the maximum using temperature can reach 1400C (0Cr21A16Nb, 0Cr27A17Mo2, etc.)
2. Low temperature coefficient of resistance
3. Lower thermal expansion coefficient than the Ni-base super-alloys.
4. High electrical resistivity
5. Good corrosion resistance under high temperature, especially under the atmosphere containing sulfides
6. High surface load
7. Creep-resistant
8. Lower raw-material cost, Lower density and cheaper price compared with Nichrome wire.
9. Superior oxidation resistance at 800-1300ºC
10. Long service life
