Bonded NdFeB has extremely high magnetic energy product and coercive force, and its high cost performance is also its advantage. Bonded NdFeB has very good mechanical characteristics. Generally, its chemical composition and surface treatment must be adjusted before it can be put into practical applications. The process of bonding NdFeB is to smelt certain raw materials into alloy steel ingots through an induction furnace, then crush them into powder and process them in a magnetic field. After forming, the embryo is sintered in a vacuum sintering furnace and tempered. In this way, an embryo with a certain magnetic energy is obtained. After grinding, drilling, cutting and other processing processes, the bonded NdFeB finished product required by the user is produced after surface treatment.
The characteristics of high energy density make bonded NdFeB very commonly used in current industrial production and electronic fields, making it possible for some mechanical equipment to be thinner and lighter. Bonded NdFeB is now mainly used in micromotors, permanent magnet electrical instruments, electronic industry, nuclear magnetic resonance, audio equipment and magnetic therapy equipment. It can also be used on the oil roads of motorcycles and cars to achieve fuel saving. Bonded NdFeB magnets are now found to have very high performance in the industrial field. We call them magnet kings and have extremely high magnetic properties. Its own mechanical properties are also quite good. The operating temperature can reach several hundred degrees Celsius. Because of its special structure, bonded NdFeB is hard and stable, and has a reasonable price, so its application is very common. The chemical activity of bonded NdFeB is very active, and its surface needs to be treated with a layer of coating for practical application.
