 ASTM A753
encompasses a group of Nickel-Iron soft magnetic alloys with the unique
 characteristic of very high magnetic permeability, high electrical resistivity, low coercive
 field strength and low core loss.  They are very effective at shielding electrical components
 from static or low-frequency magnetic fields, which cannot be as effectively attenuated by
 other alloys.  They are heavily used in laminations and moderate frequency toroidal
 tape-wound transformer cores.

 Chemical Composition and Specifications:  Typically...
