(Summary description)Permanent magnet materials, also known as "hard magnetic materials", refer to materials that can maintain constant magnetism once they are magnetized, with wide hysteresis loops, high coercivity and high remanence. There are two main categories of permanent magnet materials commonly used at present: the first category is alloy rare earth permanent magnet materials, including neodymium iron boron (NdFeB), samarium cobalt (SmCo); the second category is: ferrite permanent magnet materials ( Ferrite); the third category is: aluminum nickel cobalt (AlNiCo).

Overview of Permanent Magnet Materials

Permanent magnet material is an ancient and widely used functional material. It has been recognized by people as early as 3,000 years ago. The compass, one of the four great inventions in ancient my country, is the earliest technical application of magnets in history.

Basic knowledge of permanent magnet materials

Permanent magnet materials, also known as "hard magnetic materials", refer to materials that can maintain constant magnetism once they are magnetized, with wide hysteresis loops, high coercivity and high remanence. There are two main categories of permanent magnet materials commonly used at present: the first category is alloy rare earth permanent magnet materials, including neodymium iron boron (NdFeB), samarium cobalt (SmCo); the second category is: ferrite permanent magnet materials ( Ferrite); the third category is: aluminum nickel cobalt (AlNiCo).

Permanent magnet material

NdFeB (NdFeB) belongs to the third-generation rare earth permanent magnet material. It has the characteristics of small size, light weight and strong magnetic properties. It is the magnet with the best performance and price ratio so far. The advantages of high energy density make NdFeB permanent magnet materials the most widely used in modern industry and electronic technology.
