1.The picture of 1Cr21Al4 resistant electric alloy flat wire
1Cr21Al4 resistant electric alloy flat wire is characterized by excellent oxidation resistance and very good form stability resulting in
long element life. They are typically used in electrical heating elements in industrial furnaces and home
appliances. FeCrAl alloys have higher service temperature then NiCr alloys,but lower stability and flexibility.
1Cr21Al4 resistant electric alloy flat wire is widely used in heat treatment equipment, auto parts, iron and steel manufacturing,
aluminum industry, metallurgical equipment, petrochemical equipment, glass machinery, ceramic machinery,
food machinery, pharmaceutical machinery, power engineering industry, and residential appliances.
