Magnetic holders with neodymium magnets featuring an external thread offer robust accessories, used in many fields, such as construction, agriculture, or advertising. Their design relies on a high-performance NdFeB magnet, installed in metal casing coated with zinc and nickel. Threaded pin ranging from M4–M8 allows installation into threaded holes, which enables to screw in nameplates, lighting, tools. Thanks to a focused magnetic field, such mounts provide a pulling strength of up to 68 kg, depending on the model and size. Their use include not only industrial operations and DIY projects. Some versions feature a protective layer, that protects surfaces from damage and improves moisture resistance. However, it is important to remember neodymium magnets are brittle and may break under over-tightened mounting. Careful handling is advised, and they should be stored away from magnetic cards and electronic devices. For best quality, it is advisable to choose models from trusted manufacturers.

Advantages and disadvantages of neodymium magnets NdFeB.

In addition to their exceptional magnetic power, neodymium magnets offer the following advantages:

They have unchanged lifting capacity, and over around 10 years their attraction force decreases symbolically – ~1% (in testing),
They are highly resistant to demagnetization caused by external field interference,
Because of the lustrous layer of silver, the component looks high-end,
They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
Thanks to their exceptional temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C or more,
With the option for customized forming and personalized design, these magnets can be produced in numerous shapes and sizes, greatly improving application potential,
Wide application in new technology industries – they serve a purpose in hard drives, electric drives, medical equipment as well as technologically developed systems,
Thanks to their concentrated strength, small magnets offer high magnetic performance, while occupying minimal space,

Disadvantages of magnetic elements:

They can break when subjected to a sudden impact. If the magnets are exposed to physical collisions, they should be placed in a metal holder. The steel housing, in the form of a holder, protects the magnet from breakage and enhances its overall strength,
High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent loss in performance (depending on shape). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
Due to corrosion risk in humid conditions, it is wise to use sealed magnets made of rubber for outdoor use,
The use of a protective casing or external holder is recommended, since machining internal cuts in neodymium magnets is risky,
Safety concern from tiny pieces may arise, in case of ingestion, which is significant in the context of child safety. Moreover, small elements from these assemblies can hinder health screening once in the system,
High unit cost – neodymium magnets are more expensive than other types of magnets (e.g., ferrite), which increases the cost of large-scale applications

Handle Neodymium Magnets with Caution

Magnets are not toys, youngest should not play with them.

Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

Neodymium magnets can become demagnetized at high temperatures.

Even though magnets have been found to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

Keep neodymium magnets as far away as possible from GPS and smartphones.

Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

Neodymium magnetic are particularly fragile, resulting in their breakage.

Neodymium magnetic are delicate as well as will crack if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

Keep neodymium magnets away from people with pacemakers.

In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

Magnets attract each other within a distance of several to around 10 cm from each other. Remember not to put fingers between magnets or in their path when they attract. Magnets, depending on their size, can even cut off a finger or there can be a severe pressure or even a fracture.

The magnet is coated with nickel - be careful if you have an allergy.

Studies clearly indicate a small percentage of people who suffer from metal allergies such as nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Keep neodymium magnets away from TV, wallet, and computer HDD.

The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

Neodymium magnets are the most powerful magnets ever invented. Their power can surprise you.

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.

Pay attention!
