Block neodymium magnets (Nd-Fe-B) are composed of neodymium, iron, boron and a few transition metals. These magnets are extremely strong
for their small size, metallic in appearance and shaped in blocks.
Their max energy product can be 35MGOe~50MGOe, Block neodymium magnets are developed rapidly and applied widely due to their perfect
characteristic, rich raw material resource and reasonable price.
Block neodymium magnets are brittle and prone to chipping and cracking. They do not take
kindly to machining.
Block neodymium magnets will lose their magnetic properties if heated above 175F (80C).
Block 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.
The strong magnetic fields of neodymium magnets can also damage magnetic media such as floppy disks, credit cards,
magnetic I.D. cards, cassette tapes, video tapes or other such
devices. They can also damage televisions, VCRs, computer monitors
and other CRT displays. Never place neodymium magnets near
Block neodymium magnets have several grads: N35 block neodymium
magnets, N38 block neodymium magnets, N40 block neodymium magnets,
N42 block neodymium magnets, N45 block neodymium magnets, N48 block
neodymium magnets, N50 block neodymium magnets.
Applications of sintered neodymium magnet(blocks)-China sintered
neodymium magnet Manufacturers/suppliers
DC motors (automotive starters) and other motors
Computer rigid disc drives
magnetic resonance imaging
Attributes of Neodymium Magnet
Very high resistance to demagnetization
High energy for size
Good in ambient temperature
Material is corrosive and should be coated for long
term maximum energy output
Low working temperature for heat applications,
but higher levels of heat resistance materials
are being introduced periodically
