What Are Ferrite Magnetics? Ferrite magnetics are permanent magnetic materials made up of strontium oxide (SrO) or barium oxide (BaO) and iron oxide (Fe₂O₃). They are known for their high electrical resistivity and dielectric properties and are used in high-frequency, low-current applications, critical for electronics and telecommunications. Fe₃O₄ (magnetite), the simplest natural ferrite, has been […]
NdFeB is a rare earth permanent magnet material composed of neodymium, iron and boron. Compared with other magnetic materials, it has outstanding magnetic performance advantages, such as high remanence (Br), high coercive force (Hcj), and high magnetic energy product (BHmax). The magnetic energy product (BHmax) of this magnet is greater than that of samarium cobalt magnet, and it was the material with the largest magnetic energy product in the world at that time.
The definition of Samarium Cobalt SmCo Magnets As the second generation of rare earth permanent magnets, samarium cobalt (SmCo) magnets are made of metal samarium (Sm), cobalt (Co), copper (Cu), iron (Fe), zirconium (Zr), and other elements. Classified by structure, they are 1:5 type (SmCo5) and 2:17 type (Sm2Co17), known for their excellent magnetic properties. They have […]
The item and grade of industrial neodymium magnets are the specifications provided by manufacturers or sellers to identify magnets of different specifications and performance. These are the letters and numbers that convey the information of material composition, magnetic properties, and industrial applications. Note that different grades and items of industrial neodymium magnets affect the final […]
