Sintered Ferrite Y30BH Ring Magnet
The main materials of Sintered Ferrite include BaFe12O19 and SrFe12O19. According to the orientation of magnetic crystals, they can be divided into equilateral and heterotopic magnets. Because of its low price and moderate magnetic energy, it has become one of the most widely used magnets. Chemical composition produced by powder metallurgy: Ba/Sr 0.6 Fe2 O 3.Heat is frequently used to help fuse the particles with each other, and is known as a sintered magnet. Working temperature is left up to 4500C.
The annual output of sintered ferrite is over 300 tons. Ferrite magnets are made by ceramic technology, the quality of a material is solid, also is a brittle material, because of ferrite magnets have good temperature resistance and low prices, has become the most widely applied permanent magnets.
Ferrite permanent magnet material with sintering and injection molding (binding), the sintering process is divided into dry pressure with wet, it's about hard ferrite magnetic about classification, namely sintered permanent magnetic ferrite materials with bonded permanent magnetic ferrite materials, various and can be divided into people of the same material with the opposite sex according to their performance.
Circular magnet of the magnetic pole distribution was not certain, change is very much, although follow the principle of the most basic, but overall it's magnetic pole distribution has its own characteristics, that is to say, its magnetic poles distribution is not the only sure, but according to the production or magnetization of the specific conditions, there are many possible distribution. If such as ring, its magnetic poles can distribution in two circles on the surface, may also be distributed on the two, of course, there are may have multiple poles are in the same surface, the distribution of the specific conditions shall be conducted according to the specific situation to a certain judgement. Therefore, the distribution of magnetic poles of ring magnets is not certain, and there may be a variety of situations.
