2015 New Super strong Neodymium magnet/Sintered NdFeB Magnet Permanent Magnet
1. Sintered Neodymium-iron-boron magnets are particularly suitable for high volume production of a wide variety of shape and size ranges
2. Precise dimensional control is achieved in both processed and usually the component does not require further machining
3. High remanence, high coercive force, high maximum energy and are easily formed into various of sizes and shapes, So they have been widely used in commercially available fields
4. The majority of NdFeB magnets is anisotropic and can only be magnetized in the orientation direction
5. Surface treatments are needed and can be done according to customers' requirements to protect magnet
6. Coating: Ni, Zn, gold, silver, epoxy and chemical plating Ni
7. Materials: Rare earth, neodymium-iron-boron
8. Shapes: Block, ring, disk, disc or according to your drawings
9. Applications: Sensors, motors, rotors, wind turbines/wind generators, loudspeakers, magnetic hooks and holder, filters and automobiles
We 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...
