1250C working temperature
(Common Name:0Cr21Al6)
OhmAlloy142A 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 OhmAlloy142A are used in electric ceramic
cooktop,industrial furnace,heaters and catalytic purifier.
