Mounting bases with magnets featuring female thread can be versatile accessories, used in industrial and everyday applications, such as construction. They contain a magnet, typically NdFeB, embedded within a metal housing, covered with Zn layer for corrosion protection. The internal thread, available in sizes from M4 to M8, allows insertion of bolts, which facilitates assembly of various items, like signs, instruments, or lamps. They operate thanks to a powerful magnetic zone, that focuses in the contact area, providing load capacity from 1.3 kg to 60 kg, based on mounting dimensions. They are especially useful in vehicle manufacturing, for example, for securing car body components, and also in advertising, for hanging banners. Certain types come with a rubber shell, e.g. in black or yellow colors, helping prevent surface damage and increases resistance to dampness. Advantages cover great strength, ease of installation thanks to the thread, as well as the option to move massive steel components. Still, the grip strength depends on surface thickness, type of steel, or distance between the holder and the component. Preventing mechanical shocks is crucial, as NdFeB magnets are brittle, and overtightening the screw may be dangerous. In addition, a strong magnetic field may affect electronic devices, 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 their strong holding force, neodymium magnets have these key benefits:

They retain their magnetic properties for nearly 10 years – the drop is just ~1% (according to analyses),
They protect against demagnetization induced by surrounding magnetic influence effectively,
Thanks to the glossy finish and silver coating, they have an visually attractive appearance,
They have extremely strong magnetic induction on the surface of the magnet,
Neodymium magnets are known for exceptionally strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the geometry),
The ability for precise shaping or adjustment to custom needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which extends the scope of their use cases,
Important function in cutting-edge sectors – they are used in data storage devices, electric drives, clinical machines or even other advanced devices,
Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in small dimensions, which allows for use in small systems

Disadvantages of rare earth magnets:

They are fragile when subjected to a strong impact. If the magnets are exposed to external force, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from breakage while also reinforces its overall strength,
Magnets lose magnetic efficiency when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (influenced by the magnet’s structure). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
They rust in a damp environment. If exposed to rain, we recommend using moisture-resistant magnets, such as those made of rubber,
Using a cover – such as a magnetic holder – is advised due to the challenges in manufacturing complex structures directly in the magnet,
Health risk from tiny pieces may arise, in case of ingestion, which is significant in the family environments. Moreover, minuscule fragments from these assemblies have the potential to complicate medical imaging if inside the body,
Higher purchase price is one of the drawbacks compared to ceramic magnets, especially in budget-sensitive applications

Caution with Neodymium Magnets

The magnet is coated with nickel - be careful 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.

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.

Neodymium magnets can demagnetize 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.

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

In the case of holding a finger in the path of a neodymium magnet, in that situation, a cut or a fracture may occur.

Do not bring neodymium magnets close to GPS and smartphones.

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.

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

Neodymium magnets produce intense magnetic fields that 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 videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Neodymium magnets should not be around youngest children.

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

Neodymium magnets are not recommended for people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Neodymium magnets are noted for being fragile, which can cause them to become damaged.

Neodymium magnets are characterized by considerable fragility. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.

Neodymium magnets are among the most powerful magnets on Earth. The astonishing force they generate between each other can shock you.

On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.

Caution!
