sintered neodymium magnet(discs)
Never allow neodymium magnets near a person with a pacemaker or similar medical aid. The strong magnetic fields of the magnet can affect the operation of such devices.
Neodymium magnets are brittle and prone to chipping and cracking. They do not take kindly to machining.
Neodymium magnets will lose their magnetic properties if heated above 175°F (80°C).
Neodymium magnets should never be burned, as burning them will create toxic fumes.
Like any tool or toy, neodymium magnets can be fun and useful, but must always be treated with care.
Neodymium magnets (NdFeB) are composed of neodymium, iron, boron and a few transition metals.
These magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discs. Their max energy product can be 35MGOe~50MGOe, Neodymium magnets are developed rapidly and applied widely due to their perfect characteristic, rich raw material resource and reasonable price.
路DC motors (automotive starters) and other motors
路Computer rigid disc drives
路magnetic resonance imaging
路Very high resistance to demagnetization
路High energy for size
路Good in ambient temperature
路Material is corrosive and should be coated for long
term maximum energy output
路Low working temperature for heat applications,
but higher levels of heat resistance materials
are being introduced periodically
