Cylindrical Neodymium Magnets i.e. MW 6x1 / N38 are magnets created of neodymium in a cylindrical shape. They are valued for their extremely powerful magnetic properties, which outperform ordinary iron magnets. Thanks to their power, they are frequently used in products that require strong adhesion. The standard temperature resistance of such magnets is 80 degrees C, but for cylindrical magnets, this temperature increases with the growth of the magnet. Additionally, various special coatings, such as nickel, gold, or chrome, are often applied to the surface of neodymium magnets to increase their durability to corrosion. The cylindrical shape is as well one of the most popular among neodymium magnets. The magnet designated MW 6x1 / N38 with a magnetic lifting capacity of ${capacity} kg weighs only ${weight} grams.

Cylindrical neodymium magnets, also known as Nd₂Fe₁₄B, are the strongest known material for magnet production. The technology of their production requires a specialized approach 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, although neodymium is part of the strongest magnets, they are susceptible to corrosion in humid environments. Therefore, they are coated with a coating 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, are brittle, which requires special caution 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, as well as 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, 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 website for the latest information and offers, and before visiting, please call.

Although, cylindrical neodymium magnets are very useful in various applications, they can also constitute certain dangers. Due to their significant magnetic power, they can attract metallic objects with uncontrolled force, which can lead to crushing skin or other surfaces, especially hands. One should not use neodymium magnets near electronic devices 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 handy, they should be handled carefully.

Neodymium magnets, with the formula Nd₂Fe₁₄B, are currently the strongest available magnets on the market. They are produced through a complicated sintering process, which involves fusing special alloys of neodymium with additional metals and then shaping and heat treating. Their amazing magnetic strength comes from the specific production technology and chemical composition.
In terms of properties in different environments, neodymium magnets are sensitive to corrosion, especially in conditions of high humidity. Therefore, they are often coated with coatings, such as epoxy, to shield them from environmental factors and prolong their durability. High temperatures exceeding 130°C can result in a deterioration of their magnetic strength, although there are particular types of neodymium magnets that can tolerate temperatures up to 230°C.
As for potential dangers, it is important to avoid using neodymium magnets in acidic environments, basic environments, organic or solvent environments, unless they are adequately insulated. Additionally, their use is not recommended in water, oil, or in an atmosphere containing hydrogen, as they may forfeit their magnetic strength.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to immense strength, neodymium magnets have the following advantages:

They do not lose their strength (of the magnet). After approximately 10 years, their power decreases by only ~1% (theoretically),
They are exceptionally resistant to demagnetization caused by an external magnetic field,
By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
They have exceptionally high magnetic induction on the surface of the magnet,
By using an appropriate combination of materials, they can achieve high thermal resistance, allowing them to operate at temperatures up to 230°C and above...
Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
Wide application in the industry of new technologies – are used in HDD drives, electric drive mechanisms, medical apparatus and very highly developed apparatuses.

Disadvantages of neodymium magnets:

They can break when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts, and at the same time increases its overall strength,
Magnets lose their power due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent reduction in strength (although it is worth noting that this is dependent on the form and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
Possible danger associated with microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. It's also worth noting that small elements of these magnets have the potential to complicate diagnosis in case of swallowing.

Exercise Caution with Neodymium Magnets

Magnets made of neodymium are highly susceptible to damage, leading to shattering.

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

Neodymium magnets can demagnetize at high temperatures.

Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.

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

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

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.

Do not bring neodymium magnets close to GPS and smartphones.

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

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.

Neodymium magnets are the most powerful, most remarkable magnets on the planet, and the surprising force between them can shock you at first.

To use magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

Avoid contact with neodymium magnets if you have a nickel 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.

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

Neodymium magnets produce strong magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Keep neodymium magnets far from youngest children.

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