  Amorphous & Nanocrystalline Ribbon Products Available from SAT in 2020 SAT AMORPHOUS  is one of the main manufacturers of iron-based amorphous nanocrystalline cores in China, and an important supplier of nanocrystalline core products from world-renowned groups such as ABB, SE, SMA.  Core products  include toroidal cores, c cut cores, etc. Under the existing production capacity,  SAT AMORPHOUS  provides high-frequency magnetic product designs and competitive soft magnetic core prices. Characteristics The characteristics of the amorphous ribbon are as follows: 1. Amorphous alloy does not have a regular crystal structure like other magnetic materials, and the arrangement of all atoms in amorphous metal is irregular. 2. The resistance value of the amorphous metal is about three times that of crystal. 3. It is prepared by rapidly cooling the melt (about 1,000,000 Celsius degrees per second). This method prevents atoms from arranging into a stable crystal form, resulting in a metastabl

Research on the Effect of Clamping Force on Amorphous Alloy Magnetic Properties and Core Vibration

Amorphous alloy materials   are known for energy saving. Amorphous power transformers have lower core losses than silicon steel transformers, but the magnetostriction coefficient of amorphous alloys is large, which will result in greater core vibration of the amorphous transformer during operation, and the noise level varies The increase. Electromagnetic vibration not only affects the service life of equipment, but also causes more and more attention to the noise environment. Therefore, how to design and manufacture amorphous power transformers with low vibration and noise has become an urgent problem to be solved in its promotion and application. Scientists measured the magnetic properties of the amorphous strip and the amorphous wound core respectively, and obtained the magnetization and magnetostrictive properties of the core under different clamping forces. Based on the measurement data, the magnetic field and stress vibration of the amorphous iron core under different clamping for

6  Applications of Nanocrystalline Inductive Components Nowadays and In The Future Author: Octavius Chung Due to the excellent performance of soft magnetic materials and their unique combination, nanocrystalline materials have become more and more important, mainly reflected in the further improvement of future advanced power electronic systems. Applications such as energy generation and distribution, energy measurement, and management. Compared with the existing conventional soft magnetic materials ,  the use of nanocrystalline cores makes these applications more efficient, reliable, portable, compact, and smart. Nanocrystalline cores and components are playing a more important role in global smart grid projects. 1.  ELCB ELCB was equipped with Permalloy (NiFe) cores many years ago. In recent years, more and more NiFe magnetic cores are being replaced by  nanocrystalline cores . Since the penetration rate has doubled and the volume has been reduced by nearly half, the cost of the solu
