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.
