NbCuFeSiB nanocrystalline soft magnetic material is utilized for preparing amorphous strip process, firstly obtaining amorphous materials, after heat treatment microstructure formation of size 20nm alpha Fe ( SI ) microcrystalline, while the performance of excellent soft magnetic properties, and is therefore called the super microcrystalline material or nanometer materials.
In amorphous and nanocrystalline soft magnetic materials have been found, the widespread use of the soft magnetic material is silicon steel, permalloy, ferrite and amorphous alloy. They are switching power supply, power, electronic instruments, meters ranks plays an important role, but each has its own characteristics. Silicon steel with high saturation magnetic induction, but its effective permeability is low, especially in the high frequency range; ferrite high frequency loss characteristic is good, but the saturation magnetic induction and magnetic permeability is low; permalloy has a higher initial permeability, low coercivity Hc, magnetic properties of stable, but Bs is not high enough, the frequency is more than 10KHz, loss and the effective permeability is not ideal, the price more expensive, complicated processing and heat treatment. Cobalt base amorphous alloys with high magnetic permeability, over a wide frequency range has a low loss, but low values of Bs, expensive; and with a high Bs value and low price of iron based amorphous alloy, due to its effective magnetic permeability values are low and limits its application. Nanocrystalline alloy having excellent magnetic properties, high permeability ( o = 100000, M = 1000000 ), high saturation magnetic induction ( Bs = 1.2T ), low loss ( P0.2 / 50KHz = 15W / kg ), which can replace the present market all the soft magnetic material, widely used in large power switch power source, magnetic amplifier, high frequency transformer, high frequency chokes, electromagnetic residual current protection circuit breaker, a current transformer, with a very broad application prospects.

( 1k101 ) of iron base amorphous alloy ( Fe-based amorphous alloys )
Iron base amorphous alloy is composed of 80%Fe and 20%Si, B metal elements, it has high saturation magnetic induction intensity ( 1.54T ), permeability, exciting current and loss all respects superior to silicon steel sheet characteristics, especially the low iron loss ( for grain-oriented silicon steel piece 1 / 31 / 5 ), instead of silicon steel do 6070% distribution transformer energy saving. Iron base amorphous alloy strip thickness of about 0.03mm, widely used in transformers, switching power supply, a pulse transformer, magnetic amplifier, inverter intermediate-frequency transformer and iron core, suitable for 10kHz following frequency using
( 1k107 ) of Fe-based nanocrystalline alloy ( Nanocrystalline alloy )
Iron based amorphous and nanocrystalline alloy is composed of iron element, adding a small amount of Nb, Cu, Si, B elements alloy by rapid solidification process the formation of an amorphous material, this amorphous material after heat treatment can obtain the diameter of 1020 nm microcrystalline, dispersed in the amorphous matrix, known as microcrystalline and nanocrystalline materials, or nanocrystalline materials. Nanocrystalline materials have excellent magnetic properties: high saturation magnetic induction ( 1.2T ), high initial permeability ( 8 x 104 ), low Hc ( 0.32A / M ), high induction frequency of low loss ( P0.5T / 20kHz = 30W / kg ), resistivity 80 ohm / cm, than permalloy ( 50-60 u OMEGA / cm ) high, the longitudinal or transverse magnetic field treatment, can obtain high Br ( 0.9) or low Br value ( 1000Gs ). Is currently on the market the best comprehensive properties materials; suitable frequency range: 50Hz-100kHz, the optimal frequency range: 20kHz-50kHz. Widely used in switching power supply, inverter power source, magnetic amplifier, high-frequency transformer, high frequency transformer, high frequency choke coil iron core, current transformer, leakage protection switch, a common mode inductor core.
