FeCrAl Foil For Metallic Catalyst Substrate
FeCrAl alloy is a group of ferritic chromium steels, which contains high contents of aluminium and chromium in combination with rare earth elements(Lanthanum, Cer, Yttrium, Hafnium, etc.), possesses good high temperature stability.
Based on traditional FeCrAl resistance alloys, we have developed NW CrAl4 and NW CrAl6 with lower C content which is less than 0.03%, with higher aluminium content in combination with precisely adjusted additions of rare earth elements.
Features
FeCrAl foil produced by NIWIRE has good mechanical properties, thermal stability, thermal conductivity and oxidation resistance against high temperature.
