Neodymium magnets are part of the Rare earth magnets group. These magnets are the most powerful permanent magnets produced commercially. They are the most popular magnets due to their excellent power and compact size.
Even a small magnet that weighs only 2 grams has a holding power of 1700 grams.
They have high coercivity offering excellent resistance to demagnetization even better than ferrite and alnico magnets.
Neodymium magnets are available in various temperature grades that can handle from 80 Degrees Celsius up to 220 Degrees Celsius.
Neodymium magnets are available in different grades from N25 – N55 grade. The most popular grade is however N38 (Special grades are available upon request).
Neodymium magnets are brittle and can corrode and are therefore normally nickel-coated (Other coatings are available on request).
Neodymium magnets can be produced in relatively small sizes. (Custom-made sizes and grades are available on request)
Please note that because these magnets are very hard and strong, they are also brittle which can cause them to break when not handled with care.
