Cylindrical Neodymium Magnets i.e. MW 35x5 / N38 are magnets made of neodymium in a cylinder form. They are known for their very strong magnetic properties, which outperform ordinary iron magnets. Because of their power, they are often employed in devices that require powerful holding. The standard temperature resistance of these magnets is 80 degrees C, but for magnets in a cylindrical form, this temperature rises 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 also very popular among neodymium magnets. The magnet named MW 35x5 / N38 with a magnetic strength 9.68 kg weighs only 36.08 grams.

Cylindrical neodymium magnets, also known as Nd₂Fe₁₄B, are the strongest known material for magnet production. The technology of their production is complicated and includes melting 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 are made available for use in many applications, such as electric motors, audio-video equipment, and in the automotive and aerospace industries.
Moreover, although neodymium is a component of the strongest magnets, they are prone to corrosion in humid environments. For this reason, they are coated with a thin layer of silver to protect them from corrosion. It's worth noting that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, are brittle, which requires care during their handling. Therefore, any mechanical processing should be done before they are magnetized.

In terms of safety, there are several recommendations regarding the use of these magnets. It is advisable to avoid their use in acidic, basic, organic environments or in solvents, as well as in water or oil. Furthermore, they can distort 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 is available directly in the contact tab. It is recommended to visit the site for the latest information as well as promotions, and before visiting, we recommend calling.

Due to their power, cylindrical neodymium magnets are useful in many applications, they can also pose certain dangers. Because of their significant magnetic power, they can pull metallic objects with great force, which can lead to crushing skin or other materials, especially fingers. One should not use neodymium magnets near equipment or data storage devices, such as credit cards, as they can damage these devices in terms of magnetic recording. Furthermore, neodymium magnets are susceptible 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 with due caution.

Neodymium magnets, with the formula Nd₂Fe₁₄B, are currently the strongest available 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 heat treating. Their amazing magnetic strength comes from the unique production technology and chemical composition.
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 gold, 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 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 cylindrical magnet of class N52 and N50 is a powerful and strong magnetic product shaped like a cylinder, that offers strong holding power and versatile application. Very good price, fast shipping, ruggedness and versatility.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

They have stable power, and over nearly ten years their performance decreases symbolically – ~1% (according to theory),
Their ability to resist magnetic interference from external fields is notable,
In other words, due to the glossy nickel coating, the magnet obtains an professional appearance,
They possess intense magnetic force measurable at the magnet’s surface,
They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
Thanks to the freedom in shaping and the capability to adapt to individual requirements, neodymium magnets can be created in various configurations, which broadens their application range,
Significant impact in modern technologies – they are utilized in HDDs, electric motors, clinical machines along with sophisticated instruments,
Thanks to their power density, small magnets offer high magnetic performance, while occupying minimal space,

Disadvantages of magnetic elements:

They are prone to breaking when subjected to a powerful impact. If the magnets are exposed to mechanical hits, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage while also increases its overall durability,
Magnets lose field strength 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,
They rust in a moist environment. For outdoor use, we recommend using encapsulated magnets, such as those made of plastic,
Using a cover – such as a magnetic holder – is advised due to the challenges in manufacturing holes directly in the magnet,
Health risk related to magnet particles may arise, especially if swallowed, which is notable in the health of young users. Additionally, tiny components from these products can interfere with diagnostics once in the system,
Due to the price of neodymium, their cost is above average,

Be Cautious with Neodymium Magnets

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.

Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.

The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also destroy videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

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

Neodymium magnets can become demagnetized at high temperatures.

Even though magnets have been observed to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

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

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.

It is essential to maintain neodymium magnets away from children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

Neodymium magnetic are particularly fragile, which leads to damage.

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.

Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.

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

The magnet is coated with nickel. Therefore, exercise caution if you have an allergy.

Studies clearly indicate a small percentage of people who suffer from metal allergies such as 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.

Exercise caution!
