Characteristics of NdFeB Magnet Processing Materials and Their Market Use
NdFeB magnet is a kind of magnet widely used at present, not only small, light weight, but also has a very strong magnetic, can be said to be the best cost-effective magnet, the following describes the characteristics of NdFeB magnet processing materials and its market use:
NdFeB magnet processing material composition:
It is expected that there will be no magnetic material replacing NdFeB magnets in the next 20 years. The main raw materials for the production of NdFeB magnets are rare-earth metal antimony, rare-earth metal antimony, pure iron, aluminum, boron iron alloy and other rare-earth raw materials.
NdFeB Magnets Market Usage:
NdFeB magnets as the third generation of rare earth permanent magnet materials have high performance. They are widely used in energy, transportation, machinery, medical, IT, home appliances and other industries, especially with the development of knowledge economy represented by information technology. The use of functional materials such as rare earth permanent magnets, NdFeB, and other industries will continue to bring new applications, which will bring a broader market perspective to the NdFeB industry.
The neodymium-iron-boron magnet is a tetragonal crystal formed of neodymium, iron, and boron (Nd2Fe14B). In 1982, Masato Sagawa of Sumitomo Metals discovered a neodymium magnet. The magnetic energy product (BHmax) of this magnet is larger than that of a samarium-cobalt magnet, and it is the material with the largest energy product at that time in the world. [24] Later, Sumitomo Metal developed the powder metallurgy process, and General Motors developed the melt-spinning process to produce neodymium-iron-boron magnets. [25] This magnet is the most powerful permanent magnet in the world today, and is also the rare earth magnet most commonly used. It is widely used in electronic products such as hard disks, mobile phones, earphones, and battery-powered tools.
