Rectangle Magnets, Permanent Magnets, Rare earth magnets
1) High Permanence
2) High Coercive Force
3) High Magnetic PowerDetailed Information of NdFeB Magnets:Name: Magnet products, Permanent Magnets, Rare earth magnetsSintered NdFeB magnetBeing made from Neodymium, Iron, Boron and other elementsHigh remanence, high coercive force, high energy, etc
High resistance to magnetic demagnetization
Excellent cost to performance ratio
Not suitable for application which exposed to high temperatures.
Widely used in mini-motors, wind generators, meters, sensors, speakers, magnetic suspension system, magnetic transmission machine and other industrial applications.
Very easy to corrosion in humid environments, so it is necessory to do the surface treatment according customers' requirements. We can offer the coatings, such as Zinc, Nickel, Nickel-copper-nickel, Silver, gold-plating, Epoxy coating, etcGrade: N35-N52, N35M-48M, N33H-N44H, N30SH-N42SH, N28UH-N38UH, N28EH-N35EHNote: OEM Service, High quality, fast delivery, best serviceabout Sintered Neodymium MagnetSince the foundation of our company in 2005, we have been engaged in the manufacturing and distributing of magnetic materials. At present, we are capable of producing 220 tons of NdFeB per year and our annual sales rises to 6 million dollars. Our products are mainly exported to Europe, America and Southeast Asia. Half of our products are purchased by American or German loudspeaker manufacturers, such as the JBL and AR in the US as well as the Heco in Germany. Thirty percent are sold to electric machine manufacturers like the Italian Cear and the Chinese Baolai. We have earned good reputation in this industry and established long-term cooperative relationship with multiple clients.
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.
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.
