D25x5mm Round Magnets And Super Magnets In The Magnetic Materials

Product Detail

Among those famous d25x5mm round magnets and super magnets in the magnetic materials manufacturers, it is a professional supplier in China, welcome to wholesale d25x5mm round magnets and super magnets in the magnetic materials from our factory.

D25x5mm Round magnets and super magnets in the magnetic materials  

 

Neodymium disc magnets (Nd-Fe-B) are made from the most powerful magnetic materials in the world. These supper magnets have superb strength for their size. Supper magnets are composed of neodymium, iron, boron and a few transition metals. Strongest magnet has many advantages like high coercive force, high energy, high performance/ cost ratio and can be easily formed into various shapes and widely used in many fields such as aviation, electronics, instruments, meters, DC motors, Liner motors, MRI, medical and health products. Strongest magnet is the third generation of rare earth permanent magnet and at the same time the most powerful and advanced commercialized permanent magnet today.

 

Following regular size of D25x5mm round magnets are popular in many applications.
