Cylindrical Neodymium Magnets i.e. MW 22x10 / N38 are magnets created of neodymium in a cylindrical shape. They are valued for their very strong magnetic properties, which outperform traditional ferrite magnets. Thanks to their strength, they are often employed in products that need powerful holding. The standard temperature resistance of these magnets is 80°C, but for cylindrical magnets, this temperature increases with their height. Moreover, various special coatings, such as nickel, gold, or chrome, are frequently applied to the surface of neodymium magnets to enhance their durability to corrosion. The shape of a cylinder is also very popular among neodymium magnets. The magnet designated MW 22x10 / N38 and a magnetic strength 12.16 kg weighs only 28.51 grams.

Cylindrical neodymium magnets, also known as Nd₂Fe₁₄B, are the strongest known material for magnet production. Their production process is complicated and includes melting special neodymium alloys along with other metals such as iron and boron. After appropriate processing, such as heat and mechanical treatment, the magnets are made available for use in varied applications, including electric motors, audio-video equipment, and in the automotive and aerospace industries.
Moreover, even though neodymium is part of the strongest magnets, they are susceptible to corrosion in humid environments. Therefore, they are coated with a thin layer of nickel to increase their durability. Interestingly that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, are brittle, which requires care during their handling. For this reason, any mechanical processing should be done before they are magnetized.

In terms of safety, there are many recommendations regarding the use of these magnets. It is advisable to avoid their use in acidic, basic, organic environments or where solvents are present, and also in water or oil. Furthermore, they can damage data on magnetic cards and hard drives, although data deletion using a neodymium magnet is not guaranteed.

In terms of purchasing of cylindrical neodymium magnets, several enterprises offer such products. One of the recommended suppliers is our company Dhit, located in Ożarów Mazowiecki, the address can be found directly in the contact tab. It is recommended to check the site for the current information as well as offers, and before visiting, we recommend calling.

Due to their strength, cylindrical neodymium magnets are practical in various applications, they can also pose certain dangers. Due to their significant magnetic power, they can pull metallic objects with uncontrolled force, which can lead to damaging skin as well as other surfaces, especially hands. Do not use neodymium magnets near equipment or data storage devices, such as credit cards, as they can destroy these devices in terms of magnetic recording. Furthermore, neodymium magnets are prone to corrosion in humid environments, therefore they are coated with a thin e.g., nickel layer. Generally, although they are very useful, they should be handled carefully.

Neodymium magnets, with the formula Nd₂Fe₁₄B, are at this time the strong magnets on the market. They are produced through a advanced sintering process, which involves melting special alloys of neodymium with other metals and then shaping and heat treating. Their powerful magnetic strength comes from the unique production technology and chemical composition.
In terms of properties in different environments, neodymium magnets are sensitive to corrosion, especially in humid conditions. Therefore, they are often coated with coatings, such as nickel, to shield them from environmental factors and extend their lifespan. Temperatures exceeding 130°C can result in a loss of their magnetic strength, although there are particular types of neodymium magnets that can withstand temperatures up to 230°C.
As for dangers, it is important to avoid using neodymium magnets in acidic conditions, basic environments, organic or solvent environments, unless they are properly protected. Additionally, their use is not recommended in water, oil, or in an environment containing hydrogen, as they may lose their magnetic properties.

A cylindrical neodymium magnet in classes N50 and N52 is a powerful and highly strong metallic component designed as a cylinder, featuring high force and universal applicability. Good price, 24h delivery, resistance and broad range of uses.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They retain their full power for nearly ten years – the drop is just ~1% (based on simulations),
They remain magnetized despite exposure to strong external fields,
Because of the brilliant layer of gold, the component looks aesthetically refined,
They exhibit elevated levels of magnetic induction near the outer area of the magnet,
Thanks to their enhanced 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 multiple shapes and sizes, greatly improving design adaptation,
Important function in cutting-edge sectors – they serve a purpose in computer drives, rotating machines, medical equipment along with other advanced devices,
Thanks to their power density, small magnets offer high magnetic performance, with minimal size,

Disadvantages of rare earth magnets:

They are prone to breaking when subjected to a powerful impact. If the magnets are exposed to mechanical hits, we recommend in a protective case. The steel housing, in the form of a holder, protects the magnet from fracture and additionally strengthens its overall resistance,
High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on height). 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,
They rust in a moist environment – during outdoor use, we recommend using sealed magnets, such as those made of plastic,
Using a cover – such as a magnetic holder – is advised due to the difficulty in manufacturing fine shapes directly in the magnet,
Potential hazard linked to microscopic shards may arise, when consumed by mistake, which is notable in the protection of children. Additionally, minuscule fragments from these products have the potential to complicate medical imaging once in the system,
Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications

Handle Neodymium Magnets with Caution

Neodymium magnets can demagnetize at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

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

Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional damage to the magnets.

It is essential to keep neodymium magnets out of reach from children.

Remember that neodymium magnets are not toys. Be cautious and make sure no child plays with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

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 magnets are not recommended for 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.

Avoid contact with neodymium magnets if you have a nickel 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Magnets made of neodymium are extremely fragile, leading to breaking.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. At the moment of connection between the magnets, tiny sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

Strong magnetic fields emitted by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

Neodymium Magnets can attract to each other, pinch the skin, and cause significant swellings.

If joining of neodymium magnets is not controlled, then they may crumble and crack. Remember not to move them to each other or have them firmly in hands at a distance less than 10 cm.
