Fe-Cr-Al Electric Resistance Strip (OCr21Al6Nb)

Model NO.: 0Cr21Al6Nb KanthalA1 Material: Fecral Shape: Strip Chemical Composition: Fecral Surface: Bright Resistance Tolerance: ±5% Specification: SGS Product Type: Strip Carbon Content: Low Carbon Dimensions: Customized Condition: Soft Treatment: Annealing Trademark: XL Origin: Jiangsu, China 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.
Manufactured according to international quality. System (ISO9001) Stable resistance and long-life span. High-quality and well after-sell service.
   Size range  wire: strips: thickness:0.05-5mm                                             width:5-250mm
