Neodymium Cylindrical Magnets min. MW 18x10 / N38 are magnets created of neodymium in a cylinder form. They are valued for their extremely powerful magnetic properties, which outperform traditional ferrite magnets. Because of their strength, they are often used in devices that require powerful holding. The standard temperature resistance of such magnets is 80 degrees C, but for cylindrical magnets, this temperature increases with their height. Additionally, 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 cylindrical shape is also one of the most popular among neodymium magnets. The magnet with the designation MW 18x10 / N38 with a magnetic force 9.95 kg has a weight of only 19.09 grams.

Cylindrical neodymium magnets, also known as Nd₂Fe₁₄B, are the strongest known material for magnet production. Their production process requires a specialized approach and includes sintering 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 prone to corrosion in humid environments. Therefore, they are coated with a coating of gold-nickel to increase their durability. It's worth noting that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, easily break, which requires special caution during their handling. For this reason, any mechanical processing should be done before they are magnetized.

In terms of safety, there are several 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 damage 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 suggested 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, we recommend calling.

Although, cylindrical neodymium magnets are very useful in many applications, they can also constitute certain dangers. Because of their strong magnetic power, they can pull metallic objects with significant force, which can lead to damaging skin or other surfaces, especially be careful with fingers. Do 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, thus they are coated with a thin e.g., nickel layer. In short, although they are handy, one should handle them carefully.

Neodymium magnets, with the formula neodymium-iron-boron, are currently the very strong magnets on the market. They are produced through a advanced sintering process, which involves melting special alloys of neodymium with additional metals and then forming 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 epoxy, to preserve them from environmental factors and prolong their durability. Temperatures exceeding 130°C can result in a deterioration of their magnetic properties, 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 conditions, basic conditions, 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.

Advantages and 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 strength decreases by only ~1% (theoretically),
They are exceptionally resistant to demagnetization caused by an external magnetic field,
In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an visually attractive appearance,
They have very high magnetic induction on the surface of the magnet,
Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C and above...
The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in a wide range of shapes and sizes, which amplifies their universality in usage.
Wide application in the industry of new technologies – are utilized in computer drives, electric motors, medical apparatus or very advanced devices.

Disadvantages of neodymium magnets:

They are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts, and at the same time increases its overall strength,
High temperatures can reduce the power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss in strength (although it is dependent on the shape and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
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 - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
Health risk associated with microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these devices are able to be problematic in medical diagnosis after entering the body.

Exercise Caution with Neodymium Magnets

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

Magnets will 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, because a major 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.

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.

Maintain neodymium magnets far from youngest children.

Remember that neodymium magnets are not toys. Do not allow children to play with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.

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

Strong magnetic fields emitted by neodymium magnets can destroy 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 magnets are among the most powerful magnets on Earth. The surprising force they generate between each other can shock you.

Familiarize yourself with our information to correctly handle these magnets and avoid significant swellings to your body and prevent disruption to the magnets.

Neodymium magnetic are fragile as well as can easily crack and shatter.

Neodymium magnetic are highly fragile, and by joining them in an uncontrolled manner, they will break. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable 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.

The magnet coating contains nickel, so be cautious 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Neodymium magnets can become demagnetized at high temperatures.

Despite the fact that magnets have been found 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.

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.

Avoid bringing neodymium magnets close to a phone or GPS.

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