NdFeB Magnets
Neodymium Iron Boron magnets, popularly named Neodymium Magnets, NdFeB magnets or NIB Magnets are one kind of rare earth magnets with excellent Energy Product and high Coercive Force. As an essential basic functional materials for saving energy and developing green industry, NdFeB magnets are widely used In motor, generator, elevator, sensor, separator, MRI, VCM, DVD, Mobile, phone, printer, instruments, appliances, etc.

About Mag Spring® Facility Why Us
Caution
1.Please pay full attention to avoid any finger injury when applying the magnetized product since it possesses strong magnetic force.
2. The magnetized magnets should be kept far away from floppy disks, magnetic tapes, credit CARDS, magnetic CARDS, electronic devices and electronic instrument boards, pacemakers and other medical devices or similar objects.
3.Please pay full attention to avoid any damages or chips during transport and handling since NdFeB and SmCo magnet possesses weak impact resistance.
