Hengdian Kim Dae-magnetic Factory ------ how to buy the most affordable of the magnet dimensions and tolerances a reasonable size selection: Sintered NdFeB magnet is to do the right rough material, then the needs of guests The size of reprocessing. If the design is unreasonable size will produce waste materials into the body will increase accordingly. Please choose size when customers first and our business staff to communicate more, we will give you a reasonable size. 2 magnets maintain quality of our products Dimension Tolerance: Normal for: plus or minus of plus or minus 0.03mm 0.05mm special can do large magnetic Hengdian gold factory ---- punch magnet holding the magnetic method which is also known as punch magnet magnet, is the presence of a magnetic field around the material and their own objects, there are two types of natural and man-made. Artificial magnets usually perforated metal alloy, having a ferromagnetic. Ferromagnetic quality magnet suppliers, refers to a material's magnetic state of affordable high-quality magnets, with the phenomenon of spontaneous magnetization. Some of the material after the material under the action of an external magnetic field of magnetization, even if the external magnetic field disappears, still able to maintain its state of magnetization and magnetic, which is the spontaneous magnetization. All of the permanent magnets have perforated punch punch magnets or magnets of Asia.
