Neodymium Cylindrical Magnets min. MW 30x5 / N38 are magnets created of neodymium in a cylinder form. They are valued for their very strong magnetic properties, which outperform ordinary iron magnets. Because of their power, they are often employed in devices that need strong adhesion. The typical temperature resistance of such magnets is 80 degrees C, but for cylindrical magnets, this temperature increases with the growth of the magnet. Moreover, various special coatings, such as nickel, gold, or chrome, are frequently applied to the surface of neodymium magnets to enhance their resistance to corrosion. The shape of a cylinder is as well very popular among neodymium magnets. The magnet named MW 30x5 / N38 with a magnetic lifting capacity of 8.29 kg has a weight of only 26.51 grams.

Cylindrical neodymium magnets, often referred to as Nd₂Fe₁₄B, are the strongest known material for magnet production. Their production process requires a specialized approach and includes sintering special neodymium alloys with other metals such as iron and boron. After a series of processes, such as heat and mechanical treatment, the magnets are made available 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. For this reason, they are coated with a coating of gold-nickel to increase their durability. Interestingly that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, easily break, which requires care during their handling. Therefore, 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. Additionally, they can distort data on magnetic cards and hard drives, although data deletion using a neodymium magnet is not always certain.

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

Due to their strength, cylindrical neodymium magnets are very useful in many applications, they can also constitute certain risk. Due to their strong magnetic power, they can attract metallic objects with great force, which can lead to damaging skin and other surfaces, especially be careful with fingers. One should 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. In short, although they are handy, they should be handled carefully.

Neodymium magnets, with the formula Nd₂Fe₁₄B, are currently the very strong magnets on the market. They are produced through a advanced sintering process, which involves fusing specific alloys of neodymium with other metals and then forming and heat treating. Their unmatched magnetic strength comes from the exceptional production technology and chemical structure.
In terms of properties in different environments, neodymium magnets are susceptible to corrosion, especially in humid conditions. Therefore, they are often covered with coatings, such as epoxy, to preserve them from environmental factors and prolong their durability. Temperatures exceeding 130°C can cause a deterioration of their magnetic strength, although there are specific types of neodymium magnets that can tolerate temperatures up to 230°C.
As for risks, it is important to avoid using neodymium magnets in acidic conditions, basic environments, organic or solvent environments, unless they are insulated. Additionally, their use is not recommended in wet conditions, oil, or in an environment containing hydrogen, as they may forfeit their magnetic strength.

A cylindrical neodymium magnet N52 and N50 is a strong and powerful metallic component with the shape of a cylinder, that offers high force and universal application. Very good price, 24h delivery, durability and versatility.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

They virtually do not lose power, because even after 10 years, the performance loss is only ~1% (in laboratory conditions),
Their ability to resist magnetic interference from external fields is impressive,
In other words, due to the glossy silver coating, the magnet obtains an professional appearance,
They exhibit elevated levels of magnetic induction near the outer area of the magnet,
Thanks to their high temperature resistance, they can operate (depending on the geometry) even at temperatures up to 230°C or more,
Thanks to the flexibility in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in various configurations, which expands their usage potential,
Wide application in new technology industries – they are used in data storage devices, electric drives, clinical machines as well as other advanced devices,
Thanks to their power density, small magnets offer high magnetic performance, while occupying minimal space,

Disadvantages of NdFeB magnets:

They may fracture when subjected to a powerful 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 breakage and additionally increases its overall resistance,
High temperatures may significantly reduce the strength of neodymium magnets. Typically, above 80°C, they experience permanent loss in performance (depending on size). 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 recommended to use sealed magnets made of synthetic coating for outdoor use,
The use of a protective casing or external holder is recommended, since machining internal cuts in neodymium magnets is restricted,
Health risk related to magnet particles may arise, if ingested accidentally, which is important in the context of child safety. Additionally, small elements from these magnets may hinder health screening once in the system,
Due to a complex production process, their cost is considerably higher,

Handle Neodymium Magnets with Caution

Neodymium magnets should not be near people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

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

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

Magnets made of neodymium are delicate and can easily crack as well as get damaged.

Neodymium magnets are highly fragile, and by joining them in an uncontrolled manner, they will crack. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.

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

Magnetic fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Neodymium magnets can become demagnetized 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 can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant injuries.

Magnets attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, as a serious injury may occur. Magnets, depending on their size, are able even cut off a finger or alternatively there can be a severe pressure or a fracture.

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

Neodymium magnets are not toys. Do not allow children to play 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.

Neodymium magnets are among the strongest magnets on Earth. The surprising 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.

Dust and powder from neodymium magnets are highly 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.

The magnet is coated with nickel. Therefore, exercise caution 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.
