  They are typically used in electrical heating elements in industrial furnaces and home appliances.
  FeCrAl alloys have higher service temperature than NiCr Alloys and much lower prices. But they have lower stability and flexibility, easily to be fragile after a time circle.

Our factory established in2002 and concentrated on manufacture Fecral Alloy Wire,strip,ribbon,bar and sheet for many years,including 1Cr13Al4 ,0Cr21Al4, 0Cr21Al6, 0Cr25Al5, 0Cr21Al6Nb, 0Cr27Al7Mo2  and etc. 
Strict manage,top quality and available price.

Short delivery time and well after-sell service.
