|Application of Supermalloy
Precision Supermalloy alloy is used in manufacturing components for radio engineering,telephony and telemechanics instruments.
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.
High performance magnetic cores such as toroids and stacked laminations
Magnetic shielding to protect sensitive components from extraneous magnetic fields
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
