Neodymium Magnet

Magnet

It is a molded sintering magnet with rare earth elements called Neodymium (17 : atomic number #21, #39, #57-71) and iron oxide and boron:B.
Because magnetic energy is very powerful and the price is relatively cheaper than SmCo magnets, its utilization is rapidly expanding in each direction.
However, the temperature characteristics are lower than those of other types of magnets, and it is easily oxidated, so the processing of surface is important
in manufacturing. Neodymium magnets are powerful irreplaceable magnet as widely used in disc drivers, mobile devices, environmental energy, electric vehicles
and wind power generators. Neodymium magnets are also mainly applied on camera modules, stereo devices, sensors for electronic device operation,
and other accessories. It can be applied to tablets or laptops with big advantage of its superior process-ability and strength among rare earth magnets, even in small size.
