What are the characteristics of amorphous iron cores?

Amorphous iron cores are a new type of magnetic material with many unique characteristics. Amorphous iron cores are made of amorphous iron alloys with very small grain sizes, usually at the nanometer level, so that they are structurally disordered. This structure makes amorphous iron cores have the following characteristics:

First, amorphous iron cores have low hysteresis loss and eddy current loss. Due to its structural disorder, the magnetic domain boundaries in it are shorter, and the movement resistance of the magnetic domain walls is smaller, which makes the magnetic iron core reduce energy loss and improve magnetic performance in the magnetization process.

Second, the amorphous iron core has a high saturation magnetic induction strength and low coercivity. The amorphous iron core is prepared through a rapid solidification process, which makes the atomic arrangement in the alloy more compact, increasing the efficiency of magnetization and permeability, making it saturated under a smaller magnetic field, and reducing the magnetic distortion under the action of external forces.

Again, amorphous iron cores have high resistivity and thermal stability. The disordered arrangement of the crystal lattice in the amorphous iron core makes the electrons move in it to be hindered, thus increasing the resistivity. This high resistivity makes the amorphous iron core has better thermal conductivity, but also makes it has better high temperature resistance.

In addition, the amorphous iron core also has good chemical stability and mechanical properties. Amorphous iron core preparation using rapid solidification process, so that the lattice structure is not easy to be eroded by chemical media, has good corrosion resistance. At the same time, amorphous iron core plasticity and high strength, prepared into a variety of shapes of the core has a better processing and stability.

In general, amorphous iron core has a unique structure and excellent performance, making it has a wide range of application prospects in the field of power electronics, communications, medical equipment and other fields. With the continuous development and progress of science and technology, amorphous iron core will be more and more attention, and get more widely used in various fields.
