OhmAlloy145
(Common Name:0Cr21Al6Nb, A,Alloy 835)
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.
Typical applications for OhmAlloy145 are used in industrial
electric furnace, household electrical appliance and far infrared
ray device.
