EFI Alloy 50 Strip Coil Grades
EFI Alloy 50 Non-oriented Magnetics Rotor Grade (RG)
This variation of EFI 50 is a stock item in rotor grade (RG). EFI Alloy 50 RG is cold rolled to have non-directional magnetic domains. Rotor grade material is used in motor laminations, relays and rotating components where the magnetic properties must be nondirectional.
EFI Alloy 50 Non-oriented Shielding Grade (SG)
When your next design requires an electro-magnetic interference (EMI) shield, consider this non-oriented shielding grade (SG) material as a component of the application. This alloy is made to the specifications outlined in ASTM A753. Contact us for technical assistance.
EFI Alloy 50 Oriented Magnetics Transformer Grade (TG)
Transformer grade is specially processed to produce higher permeabilities at low magnetizing forces in the directions parallel to the rolling direction. The transformer grade is used primarily in transformer laminations and tape toroids. It is available by special order. Please contact the Ed Fagan sales team for assistance with lead times at 800-348-6268.
