Stronger magnetic power
NdFeB magnets are the strongest permanent magnets, with BHmax values 5-12 times ferrites and 3-10 times Alnicos. Their coercivity is 5-10 times ferrites and 5-15 times Alnicos. The high potential magnetic energy enables lifting objects up to 640 times their weight.
More Stable
NdFeB magnets have good resistance to demagnetization and can operate stably at high temperatures. Ordinary magnets face serious demagnetization above 80°C. NdFeB magnets can withstand temperatures up to 220°C.
Smaller Size
The high magnetic strength of NdFeB allows smaller volumes of material to generate equivalent magnetic fields. This enables more compact product designs with lower weight.
