OhmAlloy153
(Common Name:0Cr27Al7Mo2)
OhmAlloy153 is a iron-chromium-aluminium alloy (FeCrAl alloy) characterized by
high resistance, low coefficient of electric resistance, higher operating temperature, good corrosion resistance under high
temperature.It is suitable for use at temperatures up to 1400°C.
Typical applications for OhmAlloy153 are used in heating element of the single crystal furnace, sintering
furnace, ceramic calcining furnace and heat treatment furnace and
diffusion furnace when the temperature is more than 1200°C.
