Neodymium Cylindrical Magnets i.e. MW 10x6 / N38 are magnets created of neodymium in a cylinder form. They are known for their extremely powerful magnetic properties, which outperform traditional ferrite magnets. Because of their strength, they are frequently 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 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 increase their resistance to corrosion. The cylindrical shape is also one of the most popular among neodymium magnets. The magnet named MW 10x6 / N38 and a magnetic strength 3.32 kg weighs only 3.53 grams.

Cylindrical neodymium magnets, often referred to 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 become ready for use in varied applications, including electric motors, audio-video equipment, and in the automotive and aerospace industries.
Moreover, even though neodymium is a component of the strongest magnets, they are susceptible 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, 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 several recommendations regarding the use of these magnets. It is advisable to avoid their use 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.

Regarding the purchase of cylindrical neodymium magnets, several enterprises 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 as well as offers, and before visiting, we recommend calling.

Due to their strength, cylindrical neodymium magnets are very practical in various applications, they can also constitute certain dangers. Due to their significant magnetic power, they can pull metallic objects with great force, which can lead to crushing skin as well as other materials, especially hands. Do 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. Furthermore, 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 with due caution.

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 melting specific alloys of neodymium with additional metals and then shaping and thermal processing. Their amazing 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 conditions of high humidity. Therefore, they are often coated with thin 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 conditions, organic or solvent environments, unless they are adequately insulated. Additionally, their use is not recommended in wet conditions, oil, or in an environment containing hydrogen, as they may forfeit their magnetic properties.

A cylindrical magnet in classes N50 and N52 is a powerful and highly strong metal object designed as a cylinder, featuring high force and broad usability. Attractive price, fast shipping, durability and versatility.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their exceptional strength, neodymium magnets offer the following advantages:

Their strength remains stable, and after around 10 years, it drops only by ~1% (theoretically),
They show superior resistance to demagnetization from external field exposure,
In other words, due to the metallic silver coating, the magnet obtains an stylish appearance,
They possess intense magnetic force measurable at the magnet’s surface,
Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C or more,
The ability for custom shaping as well as adaptation to specific needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which amplifies their functionality across industries,
Key role in modern technologies – they are used in data storage devices, electric motors, clinical machines as well as sophisticated instruments,
Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications

Disadvantages of magnetic elements:

They are fragile when subjected to a powerful impact. If the magnets are exposed to external force, they should be placed in a protective case. The steel housing, in the form of a holder, protects the magnet from fracture and enhances its overall durability,
High temperatures may significantly reduce the field efficiency of neodymium magnets. Typically, above 80°C, they experience permanent deterioration in performance (depending on shape). 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,
Magnets exposed to wet conditions can degrade. Therefore, for outdoor applications, we advise waterproof types made of plastic,
Limited ability to create threads in the magnet – the use of a mechanical support is recommended,
Possible threat related to magnet particles may arise, especially if swallowed, which is notable in the family environments. Furthermore, miniature parts from these magnets can hinder health screening when ingested,
Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications

Precautions

Keep neodymium magnets away from GPS and smartphones.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets can demagnetize at high temperatures.

In certain circumstances, Neodymium magnets may experience demagnetization when subjected to high temperatures.

Neodymium magnets should not be near people with pacemakers.

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 over 10 times stronger than ferrite magnets (the ones in speakers), and their power can surprise 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 flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

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 swellings.

Neodymium magnets jump and clash mutually within a distance of several to around 10 cm from each other.

If you have a nickel allergy, avoid contact with neodymium magnets.

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.

Neodymium magnets are extremely delicate, they easily break and can become damaged.

Neodymium magnets are fragile and will shatter if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. At the moment of connection between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

Do not give neodymium magnets to 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.
