Cylindrical Neodymium Magnets i.e. MW 5x3 / N38 are magnets made of neodymium in a cylinder form. They are known for their extremely powerful magnetic properties, which exceed traditional iron magnets. Thanks to their power, they are frequently used in products that need strong adhesion. The standard temperature resistance of such 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 increase their resistance to corrosion. The shape of a cylinder is as well very popular among neodymium magnets. The magnet with the designation MW 5x3 / N38 with a magnetic strength 0.83 kg has a weight of only 0.44 grams.

Cylindrical neodymium magnets, often referred to as Nd₂Fe₁₄B, are the strongest known material for magnet production. The technology of their production is complicated and includes sintering special neodymium alloys along with other metals such as iron and boron. After a series of processes, such as heat and mechanical treatment, the magnets become ready for use in many applications, including electric motors, audio-video equipment, and in the automotive and aerospace industries.
Moreover, although neodymium is a component of the strongest magnets, they are susceptible to corrosion in humid environments. Therefore, they are coated with a thin layer of nickel to protect them from corrosion. It's worth noting that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, easily break, 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. They should not be used in acidic, basic, organic environments or in solvents, 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 always certain.

Regarding the purchase of cylindrical neodymium magnets, many companies offer such products. One of the suggested suppliers is our company Dhit, located in Ożarów Mazowiecki, the address is available directly in the contact tab. It's always worth check the site for the latest information and 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. Because of their significant magnetic power, they can pull metallic objects with significant force, which can lead to damaging skin and other materials, 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. Moreover, neodymium magnets are prone to corrosion in humid environments, therefore they are coated with a thin protective layer. Generally, although they are very useful, one should handle them carefully.

Neodymium magnets, with the formula neodymium-iron-boron, 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 forming and thermal processing. Their amazing magnetic strength comes from the exceptional production technology and chemical composition.
In terms of properties in different environments, neodymium magnets are susceptible to corrosion, especially in conditions of high humidity. Therefore, they are often covered with coatings, such as epoxy, to protect them from external factors and extend their lifespan. High temperatures exceeding 130°C can cause a deterioration of their magnetic properties, although there are specific types of neodymium magnets that can withstand temperatures up to 230°C.
As for potential dangers, it is important to avoid using neodymium magnets in acidic conditions, basic environments, organic or solvent environments, unless they are adequately insulated. Additionally, their use is not recommended in water, oil, or in an environment containing hydrogen, as they may forfeit their magnetic strength.

A neodymium magnet of class N52 and N50 is a powerful and highly strong metallic component with the shape of a cylinder, that offers strong holding power and universal application. Competitive price, fast shipping, ruggedness and universal usability.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their remarkable pulling force, neodymium magnets offer the following advantages:

Their strength remains stable, and after approximately 10 years, it drops only by ~1% (according to research),
They protect against demagnetization induced by external magnetic fields very well,
In other words, due to the shiny nickel coating, the magnet obtains an stylish appearance,
They possess significant magnetic force measurable at the magnet’s surface,
With the right combination of magnetic alloys, they reach significant thermal stability, enabling operation at or above 230°C (depending on the design),
The ability for accurate shaping as well as adaptation to individual needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which amplifies their functionality across industries,
Significant impact in cutting-edge sectors – they find application in data storage devices, rotating machines, medical equipment or even other advanced devices,
Compactness – despite their small size, they generate strong force, making them ideal for precision applications

Disadvantages of rare earth magnets:

They can break when subjected to a heavy impact. If the magnets are exposed to physical collisions, they should be placed in a protective case. The steel housing, in the form of a holder, protects the magnet from damage and additionally enhances its overall robustness,
Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible field weakening (influenced by the magnet’s dimensions). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
Due to corrosion risk in humid conditions, it is wise to use sealed magnets made of protective material for outdoor use,
Using a cover – such as a magnetic holder – is advised due to the limitations in manufacturing fine shapes directly in the magnet,
Safety concern from tiny pieces may arise, especially if swallowed, which is crucial in the family environments. Additionally, small elements from these assemblies can hinder health screening if inside the body,
High unit cost – neodymium magnets are more expensive than other types of magnets (e.g., ferrite), which increases the cost of large-scale applications

Exercise Caution with Neodymium Magnets

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

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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

Neodymium magnetic are especially delicate, resulting in shattering.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. 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.

Dust and powder from neodymium magnets are highly flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Maintain neodymium magnets away from youngest children.

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 are among the strongest magnets on Earth. The astonishing force they generate between each other 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.

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

Neodymium magnets are a source of intense magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets are not recommended for people with pacemakers.

Neodymium magnets produce strong magnetic fields that can interfere 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.

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 have a finger between or alternatively on the path of attracting magnets, there may be a serious cut or a fracture.

The magnet coating contains nickel, so be cautious 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.

Neodymium magnets can demagnetize at high temperatures.

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