There are many kinds of magnets, such as sintered NdFeb, sintered samarium cobalt, injected bonded NdFeb, sintered ferrite, al-Ni Co, cast Al-Ni Co, injection magnet, fe-Cr co and so on. In addition, according to the molding method, it can be divided into more classes, and the density difference is also very big. Now our company commonly uses several kinds of magnetic material density is.
The process of each kind of magnet is also different, and even the material formula of each magnet manufacturer is not the same. Generally speaking, the lower the density of the magnet, the lower it will be, and the lighter it will be
