About the classification of magnets

2022-09-30

There are many types of magnets, which are generally divided into two categories: Permanent Magnet and soft magnetic. The magnets we call generally refer to permanent magnet magnets, and permanent magnet magnets are divided into two category metal alloy magnets M cobalt magnets (SMCO) and aluminum nickel cobalt magnets (Alnico) ferrite.

Nd-Fe-B Magnets: It is currently a magnetic function that is found to be highly found. It is called the magnetic king. It has a very high magnetic function and its large magnetic energy accumulation (BHMAX) is more than 10 times. Its mechanical processing function is also quite good. High working temperature can reach 200 ° C.
Moreover, its texture, stable function, and good cost performance, so it uses extremely wide use. However, because of its strong chemical activity, it is necessary to deal with its appearance. (Such as plating ZN, Ni, electrophoretic, passivation, etc.). Oxygen Magnet: Its main raw materials include Bafe12O19 and SRFE12O19. It is made through ceramic craftsmanship. The texture is relatively hard and it is crispy data. Because the iron oxygen magnets have good temperature resistance, low price, and moderate function, it has become become it. Use a wide range of permanent magnets.

Alnico magnet: a alloy composed of aluminum, nickel, cobalt, iron, and other trace metal elements. The casting process can be processed and produced into different scale and shape, and the processability is very good. The cast aluminum nickel cobalt permanent magnetic magnetic coefficient, the operating temperature can be as high as 600 ° C. Aluminum nickel cobalt permanent magnet products are widely used in various instrument and other use areas.
