Shopping tips

Neodymium Cylindrical Magnets min. MW 16x3 / N38 are magnets created of neodymium in a cylindrical shape. They are known for their very strong magnetic properties, which outperform ordinary ferrite magnets. Because of their strength, they are frequently employed in products that need strong adhesion. The typical temperature resistance of these 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 durability to corrosion. The cylindrical shape is as well one of the most popular among neodymium magnets. The magnet designated MW 16x3 / N38 and a magnetic lifting capacity of 2.65 kg has a weight of only 4.52 grams.
Cylindrical neodymium magnets, also known as Nd2Fe14B, represent 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 many applications, such as 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. For this reason, they are coated with a thin layer of gold 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 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. Furthermore, 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 recommended suppliers is our company Dhit, situated in Ożarów Mazowiecki, the address is available directly in the contact tab. It's always worth check the website for the latest information as well as offers, and before visiting, please call.
Although, cylindrical neodymium magnets are useful in many applications, they can also constitute certain risk. Because of their strong magnetic power, they can pull metallic objects with uncontrolled force, which can lead to crushing skin and other materials, especially hands. 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. Moreover, neodymium magnets are prone 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 very strong magnets on the market. They are produced through a advanced sintering process, which involves melting 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 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 silver, to preserve them from environmental factors and extend their lifespan. Temperatures exceeding 130°C can cause a loss of their magnetic properties, although there are specific 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 environments, basic environments, organic or solvent environments, unless they are properly protected. Additionally, their use is not recommended in water, oil, or in an environment containing hydrogen, as they may forfeit their magnetic properties.
A cylindrical magnet with classification N52 and N50 is a strong and powerful magnetic product with the shape of a cylinder, providing high force and broad usability. Attractive price, fast shipping, durability and versatility.

Advantages and disadvantages of neodymium magnets NdFeB.

Besides their stability, neodymium magnets are valued for these benefits:

  • Their strength is maintained, and after around ten years, it drops only by ~1% (according to research),
  • They protect against demagnetization induced by external magnetic influence very well,
  • Thanks to the glossy finish and silver coating, they have an aesthetic appearance,
  • They exhibit superior levels of magnetic induction near the outer area of the magnet,
  • Neodymium magnets are known for strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the shape),
  • With the option for tailored forming and personalized design, these magnets can be produced in various shapes and sizes, greatly improving engineering flexibility,
  • Wide application in modern technologies – they are used in HDDs, electric motors, medical equipment along with sophisticated instruments,
  • Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in tiny dimensions, which allows for use in miniature devices

Disadvantages of NdFeB magnets:

  • They are prone to breaking when subjected to a sudden impact. If the magnets are exposed to mechanical hits, we recommend in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from fracture and reinforces its overall strength,
  • They lose power at elevated temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the geometry and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
  • They rust in a humid environment, especially when used outside, we recommend using encapsulated magnets, such as those made of polymer,
  • Limited ability to create threads in the magnet – the use of a magnetic holder is recommended,
  • Health risk related to magnet particles may arise, in case of ingestion, which is crucial in the protection of children. Furthermore, minuscule fragments from these products can complicate medical imaging when ingested,
  • High unit cost – neodymium magnets are more expensive than other types of magnets (e.g., ferrite), which can restrict large-scale applications

Safety Precautions

Neodymium magnets can become demagnetized at high temperatures.

Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.

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.

If you have a finger between or on the path of attracting magnets, there may be a severe cut or a fracture.

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.

Do not place neodymium magnets near a computer HDD, TV, and wallet.

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, etc. devices. They can also destroy videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

Magnets made of neodymium are particularly delicate, resulting in shattering.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of collision between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

Neodymium magnets are the most powerful magnets ever created, and their power 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.

  Neodymium magnets should not be around youngest children.

Not all neodymium magnets are toys, so do not let children play with them. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

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.

Under no circumstances should neodymium magnets be brought close to 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.

People with pacemakers are advised to avoid neodymium magnets.

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.

Caution!
