OhmAlloy123
(Common Name:0Cr21Al4
Fe-Cr-Al alloy
FCHW-2, also named 0Cr21Al4, is one kind of material Fe-Cr-Al
alloy.
Fe-Cr-Al alloy has the characteristic of high resistivity,low
temperature resistance coefficient,high operating temperature,good
anti-oxidation and anti-corrosion under high temperature.
It is widely used in industrial furnace, household appliances,
industry furnace, metallurgy, machinery, aircraft, automotive,
military and other industries producing heating elements and
resistance elements.
FeCrAl alloy series: OCr15Al5,1Cr13Al4, 0Cr21Al4, 0Cr21Al6, 0Cr25Al5,
0Cr21Al6Nb,0Cr27Al7Mo2, and etc
Size dimension range:
