FFP45.2X12X6.5 is a part of Ferrocore, which is a type of electrical steel used in electrical applications due to its ability to effectively reduce eddy-current losses in magnetic fields. It is a high-efficiency, low-coercive force, magnetic material that is used in wide range of electrical equipment, including motors, transformers, and generators. Ferrocore can be produced in sheet or bar forms, and is typically purchased in this part number's form - FFP45.2X12X6.5 - which includes measurements for 45.2 mm (1.78 in) width, 12 mm (0.472 in) thickness, and 6.5 mm (0.255 in) radius.
