Material information:
Such products are famous for its permanently magnetic Features. Nd-Fe-B bond have the highest magnetic properties, which
can choose the direction of magnetization of magnets and could be used to make complex cognitive shapes. Whats more, heat-resisting material and additives have been used on the magnetic coating, which can ensure an excellent stability against temperature. Besides, a special resin covering functions ensuring its good corrosion resistance.
