Mumetal is 80% nickel with additions of iron and molybdenum as main elements in turn this alloy offers an extremely high initial permeability. It is only moderately resistant to moisture and atmospheric corrosion, it used mainly in in transformer cores but is well known for its magnetic properties which are used for shielding electrical components from magnetic fields. "HYMU 80" has a minimum DC permeability of 80,000 at a flux density of 40 gauss when heat treated by the recommended procedure and test in accordance with ASTM 596

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.

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
