Nichrome ribbon for making furnace element from 50kw to 150 kw
Typical applications for OhmAlloy145 are used in industrial
electric furnace, household electrical appliance and far infrared
ray device.
OhmAlloy145 is a iron-chromium-aluminium alloy (FeCrAl alloy)
characterized by high resistance, low coefficient of electric
resistance, high operating temperature, good corrosion resistance
under high temperature.It is suitable for use at temperatures up to
1250°C.
Like nichrome, fecral has a excellent resistance to oxidation. At a
high temperature environment, thermodynamically stable aluminum
oxide will be formed on the surface of fecral alloy. The diffusion
rate D at 1200 C is 10-16cm2/sec.
By comparing with nichrome alloys, fecral has a higher resistance
and maximum operating temperature which is up to 1400 C. Fecral
also has a cheap raw material and lower density. It will save
budget. In addition, fecral has a higher surface load due to the
higher maximum temperature and longer life. It also has a better
resistance to sulphur in hot state.
