Amorphous soft magnetic alloy material is a new type of material that came out in the 1970s. Because of its advantages such as low core loss, high resistivity, good frequency characteristics, high magnetic induction strength, and strong corrosion resistance, it has caused people to Great emphasis, known as a new type of green energy-saving materials in the 21st century.
Its technical features are: the use of ultra-cooled solidification technology to make the alloy steel liquid to a thin strip material molding; using nanotechnology, made between the macroscopic and microscopic nano-state (10-20nm) soft magnetic material. The excellent soft magnetic properties of amorphous and nanocrystalline alloys come from their special structure. There are no crystal grains and grain boundaries in the amorphous alloy, and they are easy to magnetize. The grain size of the nanocrystalline alloy is smaller than the magnetic exchange length, resulting in average magnetic properties. The crystal anisotropy is small, and its magnetostriction can be brought close to zero by adjusting the composition.
