Features

Fe-based Nanocrystalline materials are superior to conventional materials and will be the best solution for your application (Figure 1.1).

Figure 1.1 μr versus Bs of different soft magnetic materials

● High saturation magnetic induction (1.25 T) and high magnetic permeability (>80,000) for small volumes and high precision

● Core loss equivalent to 1/5 of iron-based amorphous, with losses as low as 70 W/kg at 100 kHZ, 300 mT

● Saturation magnetostriction coefficient close to 0, with very low operating noise

● Excellent temperature stability, <10% change in material properties over the temperature range -50 to 120 °C

● Excellent frequency characteristics with excellent permeability and low losses over a wide frequency range

● With adjustable magnetic properties, different types of magnetic properties can be obtained by applying different transverse and vertical magnetic fields, or without magnetic field heat treatment, such as low remanence, high rectangular ratio, and high magnetic permeability
