Nanocrystalline Core Material Properties

Nanocrystalline material is one of the materials with the highest magnetic permeability at present, with high saturation magnetic induction and low iron loss. It is a new generation of green, low-carbon and environmentally friendly soft magnetic materials. We have developed a series of amorphous and nanocrystalline materials, strips, magnetic cores and component products.

Features:

The composition of the iron-based nanocrystalline material is Fe, Si, B, Cu, Nb. First, through rapid cooling technology, the nanocrystalline alloy is directly formed into an amorphous thin strip from molten steel, and then heat-treated in a vacuum or protective atmosphere to make the amorphous crystal structure into a nanoscale crystal structure. Our nanocrystalline materials. Through this revolutionary production process, we obtain superior magnetic properties, high magnetic induction, high magnetic permeability, low coercive force, and low iron loss. Nanocrystalline material is a new type of soft magnetic material that is green, low-carbon and environmentally friendly.

Application field:

Xingci nanocrystalline magnetic core series products made of iron-based nanocrystalline materials are mainly used in common mode inductors, high frequency transformers, current transformers, drive transformers, network transformers, magnetic beads, magnetic amplifiers, filter inductors, reactors, Various power electronics fields such as PFC inductors. At present, it has been widely used in switching power supply, household appliances, industrial power equipment, communication power supply, network energy, photovoltaic inverter, wind power generation, IGBT inverter power supply, high-power laser power supply and medical equipment power supply.
