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:
Wire: 0.01-10mm
Ribbons: Thickness: 0.04mm-0.75mm, Width: 0.08mm-6.0mm
Strip: Thickness: 0.04mm-0.75mm, Width: 5mm-250mm
Bar: 10-50mm
Typical applications for OhmAlloy123 are used as elements in home
appliances,melting and industrial furnace.
