NiCr alloys Advantages

1. Have higher hot and creep strength than FeCrAl alloys.
2. Better ductility after long use than FeCrAl alloys.
3. Generally have better corrosion resistance at room temperature than FeCrAl alloys.
4. Longer life span than FeCrAl.

And other FeCrAl can be used as furnace strip:1Cr13Al4,0Cr25Al5,0Cr27Al7Mo2 etc
