Our product features high quality-price ratio. With superior mechanical properties, it is easy to cut and process. The defects of the sintered neodymium magnet lie in the low Curie temperature, poor temperature characteristics, and high susceptibility to pulverization. We have provided solutions to remedy those flaws by adjusting the chemical composition and electroplating the surface. The product we offer can pass the 72-hour salt spray test and its maximum operating temperature reaches 240º C, thus satisfying the practical application requirements.Â
Our sintered neodymium magnet has been widely used for the cell phone headsets, high-end loudspeaker boxes, permanent magnet motors, micro motors, gift boxes, handbags, toys, medical instrumentations, instruments and apparatus, metal and plastic products, electronic components, electric car motors, wind turbine generators, and many other items.
