Do you know the advantages of neodymium iron boron magnets?

Neodymium iron boron (NdFeB) permanent magnet material is a permanent magnet material based on the intermetallic compound Nd2Fe14B. Neodymium iron boron has extremely high magnetic energy product and coercivity, and can absorb 640 times its own weight. The advantages of high energy density make neodymium iron boron permanent magnet materials widely used in modern industry and electronic technology, making it possible to miniaturize, lighten, and thin equipment such as instrumentation, electroacoustic motors, and magnetic separation and magnetization.

Advantages of NdFeB magnets

The advantages of neodymium iron boron magnets are high performance-to-price ratio, good mechanical properties, and easy cutting processing; the shortcomings are that the Curie temperature point is low, the temperature characteristic is poor, and it is easy to pulverize and corrode. It must be adjusted by its chemical composition and surface The treatment method can be improved to meet the requirements of practical application.

Advantages of NdFeB magnets

The manufacture of NdFeB adopts powder metallurgy technology, and the raw materials containing a certain proportion such as neodymium, dysprosium, iron, cobalt, niobium, praseodymium, aluminum, ferroboron, etc. are smelted into alloy steel ingots through an intermediate frequency induction melting furnace, and then crushed to produce 3¡«5μm powders are pressed and molded in a magnetic field. The molded green bodies are sintered in a vacuum sintering furnace to be compacted and tempered for aging. In this way, permanent magnet blanks with certain magnetic properties are obtained. After the blank is processed by grinding, drilling, slicing, etc., and then surface treatment, the finished product of NdFeB required by the user is obtained.
