EFI Alloy 79 Round Bar | Rod Inventory Ready-to-Ship

efi alloy 79 round bar rod soft magnetic alloyEd Fagan Inc. (EFI) is the leading global distributor of soft magnetic alloys in the forms of round bar and rod.  EFI Alloy 79 is a non-oriented, 80% nominal nickel, 15.5% nominal iron, 4.5% nominal molybdenum alloy.  The alloy’s properties provide a very high initial permeability and maximum permeability with minimum hysteresis loss making it a useful alloy for a wide range of applications.


Ed Fagan Inc. supplies EFI Alloy 79 manufactured to ASTM A753 (UNS N14080) and MIL N 14411C Comp 1 specifications.  Our comprehensive inventory contains EFI Alloy 79 round bar and rod in 12-foot random lengths.  Bars can be cut to length on our CNC band saws and shipped to your destination.


Ed Fagan Inc.’s Alloy 79 round bar is supplied stress relief annealed and centerless ground for machining. When all machining and processes are completed, this alloy must be ferromagnetically annealed to optimally develop final magnetic properties.  After the ferromagnetic anneal, any plastic deformation will degrade the magnetic properties. See our heat-treating page for details.
