FE-3% Si

Typical Applications:  Iron-Silicon alloy used in low-frequency AC applications, solenoids, electromagnetic- mechanical devices, armatures, relays, pole pieces and cores for high speed printers.

FE-5% Mo

Typical Applications:  Remington alloy with high flux density and low coercive force.  

Fe-35% Co

Typical Applications:  Fe-Co alloys produce the highest magnetic outputs; however, because of the high material cost, they are used for very small components.

Fe-50% Ni

Typical Applications:  Material with very low coercive force and high permeability. Used for torque motors, relays and missile components.
