Iron-based Nanocrystalline Ribbons

An amorphous ribbon is formed by rapidly quenching molten metal composed of iron, silicon, boron and a small amount of copper and niobium at 106 ° C / s. The amorphous ribbon is heat treated above the crystallization temperature to obtain nanocrystals (~10 nm) having a very small size and uniform distribution, and the microstructure has better soft magnetic properties than the amorphous alloy.

Sunbow produces various types of soft magnetic materials, including iron-based amorphous alloys and iron-based nanoalloys, and these materials are used in our products. We continually make technical improvements and develop new applications with the unique properties of these materials. Iron-based nanocrystalline materials are superior to traditional materials and will be the best solution for your application (Figure 2.1).

Figure 2.1 μr versus Bs of different soft magnetic materials

●Iron cores used in the switching power supply transformer and pulse transformer

●Iron cores used in power transformer and precision current transformer

●Iron core used in the leakage protection switch transformer

●Iron core used in filter inductor, energy storage inductor, and reactor

●EMC common mode and differential mode inductor core

●Saturation reactor, magnetic amplifier, peak suppressor core and magnetic beads

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

●Iron loss is equivalent to 1/5 of iron-based amorphous, and loss at ,100 kHZ, 300 mT is as low as 70 W/kg

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

●With excellent temperature stability, material performance change rate <10% in the temperature range of -50~120 °C

●With the excellent frequency characteristics, excellent magnetic permeability and low loss 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
