Custom Permanent Strong Disk NdFeb Magnet , N35 / N52 Sintered Neodymium Magnets

Product Description & Specification:

Sintered Neodymium (NdFeB)magnets are also referred to as “neo” magnets. They are particularly suitable for high volume production in a wide variety of shape and size. Precise dimensional control is achieved in machining processes.

Sintered NdFeB magnetic performance is widespread,and big various from different grade,Br:10.4~14.8KGs,Hci:14~35KOe,Bhmax:26~53MGOe. Due to NdFeB is corroded easily,coating is a necessary process.Electro plating,electrophoresis epoxy and Passivation are often used.Zn,Ni,Ni-Cu-Ni. Salt spray testing :24~200 Hours Max. Working temperature:80°C~230 °C. Due to NdFeB is so brittle,wall thickness need be more than 0.8mm. Max Magnetizing thickness is about 55mm. Tolerance:0.05mm or tighter.
