High function of rare earths such strong magnets, not as crisp as samarium cobalt high function of rare earth magnets, not as crisp as samarium cobalt, but using high temperature without samarium cobalt magnet. Under the normal temperature condition is also easy to oxidation, so appearance must be plating. A wafer shape, circular, square shape, tile shape. Have to choose from a variety of scale is now the highest function of magnets, ndfeb magnet and non-technical category is becoming more and more extensive use, such as adsorption magnets, toys, jewelry, etc. Looks coating processing: they plating coating quality, zinc, nickel, nickel and copper nickel electroplating copper and gold plating technology, etc. According to customer requests for goods plating options. Powerful magnet product quality advantages and disadvantages, a brief summary, is a good grasp of the function of scale control, public service discriminant coating appearance inspection and evaluation. Check the magnet flux of gaussian surface, such as test; Scale, public service can use vernier caliper measurement accuracy; Coating, coating color and brightness and bonding strength, appearance is bright and clean, and after the appearance observation magnet without peeling, and presence of edge drop horn, to evaluate the quality of the goods. Powerful magnet magnetic phenomenon that the pre-qin period our ancestors have accumulated a lot of knowledge in this field, in exploring often encounter magnetite iron ore mine is a magnet ( Main ingredients are ferroferric oxide) 。 These findings were recorded very early. 'Pipe', according to the number of the earliest documented the & other; The mountains have a magnet, copper with gold. ” Other ancient books, such as in shanhaijing have similar records. Iron absorption properties of a magnet was found early, the 'spring and autumn annals' nine volumes master piece are: & other; Goodness for iron, or quote also. ” At that time the person & other Magnetic & throughout; For & other; Kindness & throughout; They put a magnet attracts iron as a loving mother for their children. And think: & other; Stone is the mother of iron, but there are stone and not kind, loving stone attracted to his children, not goodness stones cannot be attracted. ” Chinese people used to write the magnet do & other; CiShi & throughout; , means love stone. The development of rare earth permanent magnet materials: rare earth elements have unique magnetic characteristics, in modern science and technology, rare earth materials by rare earth material as raw material is very important. According to the development of rare earth materials, can be divided into three generation: first generation, samarium cobalt 5, rare earth permanent magnet magnetic materials development in the 60 s, mainly used in military field. The second generation, rare earth permanent magnetic material samarium cobalt copper zirconium iron development in the 70 s, wide application field. The third generation, rare earth permanent magnet ndfeb magnet magnetic materials development in Japan in the 80 s. The birth of the third generation of magnetic material has attracted worldwide attention, because ndfeb magnet not only has the advantage of price and a higher magnetic intensity. Ndfeb products and neodymium iron to replace the expensive samarium cobalt and first generation and second belt products.
