15 NdFeB How made? Sintered NdFeB powder metallurgy manufacturing process is an iron-based permanent magnet material. The main steps are: formula, melting, milling, molding orientation, sintering, machining, plating processing. Guarantee the basic production process anaerobic operation, so that product performance and temperature are breakthrough improvements. Processing cost factors 16 magnet? Magnet processing costs mainly affected by the following factors: performance requirements, batch size, shape specifications, tolerances. The higher performance requirements, gift magnet, the higher the cost, gift magnet brands such as N45 N35 magnet price far higher than the price;?? The smaller the volume, the higher the processing costs; the more complex shapes, higher processing costs; more stringent tolerances processing cost is higher. Permanent magnets and the non-magnetic fraction permanent magnets. Permanent magnets may be a natural product, known as lodestone, also be made artificially produced (the strongest magnets are NdFeB magnets). Non-permanent magnet is heated to a certain temperature suddenly loses its magnetism, gift magnet lowest price, which is due to the large magnet arrangement consisting of "meta magnet" and from order to disorder caused;? Magnet loses its magnetism placed to a magnetic field, when the magnetization reaches a certain value, it is magnetized arrangement "Yuan magnet" in and from disorder to order. In fact, not a permanent magnet permanent magnet external factors will not only change the magnetic high temperature, impact will it loses its magnetism, strong magnetic fields can also change its magnetic poles and the strength of the magnetic field generated by an alternating current changes in the size of soon be to the magnetic body. ?
