Advantages and disadvantages of neodymium magnets NdFeB.

In addition to immense power, neodymium magnets have the following advantages:

• They do not lose power over time - after approximately 10 years, their power decreases by only ~1% (theoretically),
• They are exceptionally resistant to demagnetization caused by an external magnetic field,
• In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
• They have very high magnetic induction on the surface of the magnet,
• Magnetic neodymium magnets are characterized by very high magnetic induction on the surface of the magnet and can operate (depending on the form) even at temperatures of 230°C or higher...
• Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
• Wide application in advanced technologically fields – are utilized in HDD drives, electric drive mechanisms, medical devices or other advanced devices.

Disadvantages of neodymium magnets:

• They can break when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts, and at the same time increases its overall strength,
• High temperatures can reduce the power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction in strength (although it is dependent on the form and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
• Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
• The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
• Potential hazard arising from small pieces of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. It's also worth noting that miniscule components of these magnets are able to be problematic in medical diagnosis in case of swallowing.
