Super Strong Big Size Neodymium Permanent Rare Earth Ring Magnet
Strong Ndfeb Magnet Custom Size N35 permanent Ring Neodymium Magnet
Strong Ndfeb Magnet Custom Ring Neodymium Magnet
Description:
Neodymium Iron Boron (NdFeB) or ‘Neo’, is a super high power magnet material that is generally considered to be the strongest of the permanent magnet materials.They will maintain their magnetism indefinitely unless they are subjected to temperatures over 80˚C when they will then lose their magnetism permanently.High (100˚C-120˚C) and Ultra High (150˚C-180˚C) temperature versions are available for customers with specific requirements. Neo’s are Nickel plated for both cosmetic and protection reasons and this makes them bright silver in colour. These magnets are very hard and therefore machining these post production is not recommended.
They are available in a wide range of shapes and sizes. Generally the North Pole is on the largest flat face, with the South on the opposite face. We recommend extreme caution when handling even small Neo magnets as the attractant forces are very powerful which can result in injury. If they are allowed to snap together violently small sharp chips can be thrown off.
Key Advantages of Neodymium Magnet
Neodymium Magnet are the most powerful commercially produced
magnets.
Neodymium Magnet have a higher Maximum Energy Product, (BH).max,
which can easily reach 30 MGOe and even goes up to 50 MGOe.
Neodymium Magnet can replace SmCo magnets in most cases, especially
where operating temperature is less than 80 degrees Centigrade.
Neodymium Magnet has very high strength.
Relatively low cost.
Compared to Alnico and SmCo magnets, relatively easy to machine

- The grades like N48-N52 could meet your requirement on strong
power
- Standard one like N35 or N38 is okay for your normal applications
- If you have requirement on the working temperature, please note
it.
