Neodymium Cylindrical Magnets min. MW 12x50 / N38 are magnets made of neodymium in a cylindrical shape. They are known for their very strong magnetic properties, which exceed ordinary iron magnets. Because of their power, they are frequently used in products that need strong adhesion. The standard temperature resistance of such magnets is 80 degrees C, but for magnets in a cylindrical form, 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 enhance their durability to corrosion. The shape of a cylinder is as well very popular among neodymium magnets. The magnet with the designation MW 12x50 / N38 with a magnetic strength 33.18 kg weighs only 42.41 grams.

Cylindrical neodymium magnets, often referred to as Nd₂Fe₁₄B, are the strongest known material for magnet production. The technology of their production is complicated and includes sintering 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 varied 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 susceptible to corrosion in humid environments. Therefore, they are coated with a coating of gold-nickel to protect them from corrosion. Interestingly 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 several recommendations regarding the use of these magnets. They should not be used in acidic, basic, organic environments or where solvents are present, 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 guaranteed.

In terms of purchasing of cylindrical neodymium magnets, many companies offer such products. One of the suggested suppliers is our company Dhit, situated in Ożarów Mazowiecki, the address is available directly in the contact tab. It is recommended to visit the site 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. Because of their strong magnetic power, they can attract metallic objects with great force, which can lead to damaging skin as well as other surfaces, especially 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 prone to corrosion in humid environments, therefore they are coated with a thin protective layer. Generally, although they are handy, one should handle them with due caution.

Neodymium magnets, with the formula neodymium-iron-boron, are currently the strongest available magnets on the market. They are produced through a complicated sintering process, which involves fusing specific alloys of neodymium with additional metals and then shaping and thermal processing. Their powerful magnetic strength comes from the exceptional production technology and chemical composition.
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 coatings, such as nickel, to protect them from environmental factors and prolong their durability. Temperatures exceeding 130°C can cause a deterioration of their magnetic strength, although there are specific types of neodymium magnets that can tolerate temperatures up to 230°C.
As for dangers, it is important to avoid using neodymium magnets in acidic conditions, basic environments, organic or solvent environments, unless they are properly protected. 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 N52 and N50 is a strong and extremely powerful magnetic product with the shape of a cylinder, providing strong holding power and broad usability. Good price, fast shipping, resistance and multi-functionality.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Apart from their consistent holding force, neodymium magnets have these key benefits:

They virtually do not lose power, because even after ten years, the decline in efficiency is only ~1% (according to literature),
Their ability to resist magnetic interference from external fields is impressive,
The use of a decorative nickel surface provides a refined finish,
The outer field strength of the magnet shows remarkable magnetic properties,
These magnets tolerate extreme temperatures, often exceeding 230°C, when properly designed (in relation to build),
Thanks to the freedom in shaping and the capability to adapt to specific requirements, neodymium magnets can be created in diverse shapes and sizes, which broadens their application range,
Significant impact in cutting-edge sectors – they find application in HDDs, electromechanical systems, medical equipment or even technologically developed systems,
Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in tiny dimensions, which makes them ideal in compact constructions

Disadvantages of neodymium magnets:

They are prone to breaking when subjected to a heavy impact. If the magnets are exposed to external force, it is suggested to place them in a protective case. The steel housing, in the form of a holder, protects the magnet from fracture and reinforces its overall resistance,
They lose strength at increased temperatures. Most neodymium magnets experience permanent loss in strength when heated above 80°C (depending on the dimensions and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
Due to corrosion risk in humid conditions, it is wise to use sealed magnets made of synthetic coating for outdoor use,
The use of a protective casing or external holder is recommended, since machining internal cuts in neodymium magnets is difficult,
Possible threat from tiny pieces may arise, if ingested accidentally, which is important in the family environments. Moreover, tiny components from these products have the potential to interfere with diagnostics once in the system,
Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications

Handle Neodymium Magnets with Caution

Keep neodymium magnets away from TV, wallet, and computer HDD.

Neodymium magnets generate intense magnetic fields that 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.

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.

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Never bring neodymium magnets close to a phone and 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.

Neodymium magnets are the strongest magnets ever created, and their power can surprise you.

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

The magnet is coated with nickel - be careful 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.

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

Magnets will crack or alternatively crumble with careless connecting to each other. You can't move them to each other. At a distance less than 10 cm you should have them extremely firmly.

Magnets made of neodymium are noted for their fragility, which can cause them to shatter.

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, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

It is essential to maintain neodymium magnets out of reach from 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 significant injuries, and even death.

Neodymium magnets are not recommended for 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.
