Description

The soft-magnetic material NiFe16CuCr with the material number 2.4501 distinguishes itself by the highest initial and maximum permeability as well as by the lowest coercive field strength. It is applied for transformers, e.g. for totalizing current transformers (for fault-current circuit breakers), transducers, fault-current circuit breakers, relay and shielding parts, inductors, magnet amplifiers and magnetic heads as well as measurement devices. Processing properties: Formability: good Weldability: good
