Price: 0.1 USD

Sintered NdFeB magnet is the strongest magnetic permanent magnet material in the world today. Compared with traditional permanent magnet materials, it has excellent permanent magnet characteristics and high cost performance.Sintered NdFeb magnet is still the permanent magnet with the highest magnetic properties so far, and has long become a necessary functional material in many fields such as aerospace, national defense, electronic communications, clean energy, transportation, mining machinery, medical care and household appliances. Representative applications include permanent magnet motors, magnetic separation devices, nuclear magnetic resonance imaging, hard disk drives, consumer electronics and wind power. The sintered NdFeb irregular magnet produced by YanHe Magtech is often used in pipeline cleaner, magnetic locks, luggage magnetic, leather magnetic, toy magnetic, electricity meter and water meter, generator, motor, servo motor, micro motor, motor, vibration motor, etc.

Appearance: Smooth and bright surface without burrs.

Advantages: Direct forming can save production cost and production time compared with square grinding/sleeving process.
