Neodymium magnetic mounts with internal thread are versatile accessories, used in industrial as well as everyday applications, such as engineering. They contain a neodymium magnet, typically NdFeB, enclosed within a steel shell, covered with zinc for corrosion protection. The female thread, ranging from M3 to M10, enables mounting bolts, which simplifies assembly of different components, such as signs, instruments, or lamps. They operate thanks to a powerful magnetic zone, that focuses at the mounting point, ensuring load capacity ranging from one to sixty kilograms, depending on mount size. These are particularly helpful in the automotive industry, e.g. for attaching body panels, as well as in marketing, for hanging banners. Certain types have a rubber coating, e.g. in black or yellow, which protects surfaces from scratches and increases resistance to dampness. Benefits include great strength, ease of installation due to the internal threading, as well as the option to move massive steel components. Still, the holding force depends on surface thickness, material used, and the gap between holder and object. Preventing mechanical shocks is crucial, since neodymium magnets are fragile, and overtightening the screw may be dangerous. In addition, a magnetic zone may interfere with electronics, like phones or data carriers, therefore mounts should be stored away from those devices. It is recommended to choose holders from reputable manufacturers, to guarantee reliability and safety during use.

Advantages and disadvantages of neodymium magnets NdFeB.

Apart from immense strength, neodymium magnets have the following advantages:

They do not lose their strength (of the magnet). After about 10 years, their strength decreases by only ~1% (theoretically),
They protect against demagnetization caused by external magnetic field extremely well,
In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
They exhibit very high magnetic induction on the surface of the magnet,
Magnetic neodymium magnets are characterized by hugely high magnetic induction on the surface of the magnet and can operate (depending on the form) even at temperatures of 230°C or higher...
Thanks to the flexibility in shaping or the ability to adapt to specific requirements – neodymium magnets can be produced in various forms and dimensions, which expands the range of their possible uses.
Key role in modern technologies – find application in hard drives, electric motors, medical apparatus or other highly developed apparatuses.

Disadvantages of neodymium magnets:

They are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and at the same time increases its overall strength,
They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
Potential hazard associated with microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of children's health. It's also worth noting that small elements of these magnets can be problematic in medical diagnosis in case of swallowing.

Handle Neodymium Magnets Carefully

Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

If joining of neodymium magnets is not controlled, then they may crumble and crack. You can't approach them to each other. At a distance less than 10 cm you should hold them very firmly.

Neodymium magnets should not be near people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

Neodymium magnets can become demagnetized at high temperatures.

Despite the general resilience of magnets, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

Maintain neodymium magnets away from youngest children.

Neodymium magnets are not toys. Do not allow children to play with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.

Do not place neodymium magnets near a computer HDD, TV, and wallet.

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 away from these electronic devices.

Never bring neodymium magnets close to a phone and GPS.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their power can shock 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.

The magnet coating is made of nickel, so be cautious if you have an allergy.

Studies show a small percentage of people have allergies to certain metals, including 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.

Neodymium magnetic are highly fragile, they easily fall apart and can become damaged.

Neodymium magnetic are delicate and 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. At the moment of connection between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Warning!
