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
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.
