Basic Info
Model No.: OCr23Al5. OCr25Al5, OCr21Al6Nb
Product Description
Model NO.: OCr23Al5. OCr25Al5, OCr21Al6Nb Material: Fecral Application: Heating System Size Range: 0.05-1.0mm Treatment: Hydrogen Annealing Resistance Tolerance: ±5% Specification: SGS, ISO9001 HS Code: 72230000 Product Type: Wire Carbon Content: Low Carbon Shape: Wire Condition: Soft or Hard Surface: Bright Trademark: XL Origin: Jiangsu, China High resistance FeCrAl electric Resistance Alloy wire.
FeCrAl alloys are 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 than NiCr Alloys and much lower prices. But they have lower stability and flexibility, easily to be fragile after a time circle.
size range:0.01-1.0mm on spool.
high quality and prompt after-sell service,welcome to contact me for more detailed information.
