Nano Crystalline Cores

Nano crystalline cores are Iron Based cores which is a specially developed soft magnetic material with low magneto striction, high permeability (150000), saturation flux density of 1.25t and working temperature of 120 degrees celcius and above. These materials are available in widths of 5mm to 40 mm in steps of 5 mm and thickness varying from 20 microns to 30 microns.

Nano crystalline cores are very brittle and sensitive after annealing. Hence there is a need to encapsulate these cores by stainless steel casing or press board casing to avoid any changes in electrical values after winding, resin casting etc.
