PRODUCT APPLICATION
Permalloy
Permalloy is used in transformer laminations and magnetic recording head sensors,in its initial application,permalloy was wrapped around the insulated copper conductors of telecommunication cables,reducing signal distortion through improved inductive compensation of cable capacitive reactance.
mumetal
High performance magnetic cores such as toroids and stacked laminations
Magnetic shielding to protect sensitive components from extraneous magnetic fields
Magnetic sensors
Current sensors
Any delicate application requiring high permeability magnetic material, with a low coercive field and low losses, in the range from low frequency up to 1MHz
