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 celsius 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.Vikarsh Nano Technology and Alloys Private ltd is the only manufacturer in India for the Nanocrystalline Cores and Ribbons.
Because of its properties nano crystalline is slowly finding applications in GFI (Ground fault indicator) toroidal cores. And HMA (High Metering Accuracy) toroidal cores.
They are widely replacing Mu metal cores (NI FE) cores mainly because of its lower cost as compared to widely fluctuating Nickel prices.
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.
