Product Name: Bonded NdFeB Magnet Ring Model NO.: Ring Magnet Coating: Nickel Shape: Ring Application: Motor Magnet Type: Permanent Composition: NdFeB Magnet Trademark: Yuxiang Transport Package: Neutral Paper Carton Packing Specification: ROHS, SGS, CE Origin: Fujian, China (Mainland) HS Code: 850511900 Product Description Bonded NdFeB Magnet Ring Shape1, We manufactured rare earth bonded NdFeB magnet using both injection and compression moulding techniques, which particularly suit for high volumn production of awide variety of shapes and size ranges2, Precise dimensional control is achieved in both processed and usually the component does not require futher machining. Your customized orders are very welcomed..3, Injection moulded NdFeB do not normally require coating due to better corrosion resistanc, however coating is recommended for compression moulded NdFeBWe have accumulated abundant experience and established stable and credible business relationships with customers worldwide. with rich experience in dealing with all types of large and small orders, we have developed extensive contacts with many local and international freight organizations. Consequently, we are able to ship our goods safely and reliably to almost anywhere in the world...For more detail info, please feel free to visit our website or inquire us at any of your convenience.Ying JunSenior technical manager Yuxiang Magnetic Materials Ind.
