The invention concerns a treatment method which consists in coating at least one surface of a brittle thin metal strip ( 1 ) with a coating film ( 3, 3 ') comprising at least a polymer material, to obtain on the strip an adhering coat with a thickness ranging between 1 and 100 mum, modifying the working and breaking properties of the brittle thin metal strip ( 1 ); then carrying out a step wherein the brittle thin metal strip ( 1 ) is subjected to stresses, such as a cutting operation, on the brittle thin metal strip ( 1 ) coated with the film coating ( 3, 3 '). The method is particularly useful for producing magnetic parts from strips or ribbons with nanocrystalline structure.
