Neodymium Cylindrical Magnets min. MW 70x60 / N38 are magnets created of neodymium in a cylindrical shape. They are known for their very strong magnetic properties, which exceed traditional iron magnets. Because of their strength, they are often used in devices that require strong adhesion. The typical temperature resistance of such magnets is 80 degrees C, but for cylindrical magnets, this temperature rises with their height. Additionally, various special coatings, such as nickel, gold, or chrome, are often applied to the surface of neodymium magnets to enhance their resistance to corrosion. The shape of a cylinder is as well very popular among neodymium magnets. The magnet designated MW 70x60 / N38 and a magnetic strength 232.23 kg weighs only 1731.8 grams.

Cylindrical neodymium magnets, also known as Nd₂Fe₁₄B, are the strongest known material for magnet production. The technology of their production is complicated and includes melting 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 become ready for use in many applications, including electric motors, audio-video equipment, and in the automotive and aerospace industries.
Moreover, even though neodymium is part of the strongest magnets, they are susceptible to corrosion in humid environments. Therefore, they are coated with a coating of silver to increase their durability. Interestingly that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, are brittle, 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 where solvents are present, as well as 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.

Regarding the purchase of cylindrical neodymium magnets, several enterprises 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 website for the latest information and offers, and before visiting, please call.

Due to their power, cylindrical neodymium magnets are very practical in many applications, they can also pose certain risk. Because of their strong magnetic power, they can attract metallic objects with significant force, which can lead to crushing skin as well as other surfaces, especially fingers. One should not use neodymium magnets near electronic devices 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 very useful, one should handle them carefully.

Neodymium magnets, with the formula neodymium-iron-boron, are presently 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 conditions of high humidity. Therefore, they are often coated with coatings, such as silver, to shield them from external factors and prolong their durability. High temperatures exceeding 130°C can cause a reduction of their magnetic properties, although there are specific types of neodymium magnets that can withstand temperatures up to 230°C.
As for risks, it is important to avoid using neodymium magnets in acidic environments, basic conditions, organic or solvent environments, unless they are properly protected. Additionally, their use is not recommended in water, oil, or in an atmosphere containing hydrogen, as they may forfeit their magnetic strength.

Advantages and disadvantages of neodymium magnets NdFeB.

Apart from immense power, neodymium magnets have the following advantages:

They do not lose their power (of the magnet). After about 10 years, their power decreases by only ~1% (theoretically),
They are extremely resistant to demagnetization by external magnetic sources,
In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an visually attractive appearance,
They exhibit extremely high magnetic induction on the surface of the magnet,
Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C and above...
The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which expands the range of their possible uses.
Key role in advanced technologically fields – find application in HDD drives, electric motors, medical equipment or other modern machines.

Disadvantages of neodymium magnets:

They can break as they are extremely fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
They rust in a humid environment - during 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 can be dangerous, when accidentally ingested, which becomes significant in the context of child safety. It's also worth noting that tiny parts of these products have the potential to be problematic in medical diagnosis in case of swallowing.

Be Cautious with Neodymium Magnets

Neodymium magnets should not be in the vicinity youngest children.

Neodymium magnets are not toys. Be cautious and make sure no child plays with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.

Neodymium magnets are the most powerful magnets ever created, and their strength can surprise you.

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

Magnets may crack or 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 strongly.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

Neodymium magnets produce intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Magnets made of neodymium are delicate and can easily break and get damaged.

Neodymium magnetic are delicate and will break 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 collision between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

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, or other devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Neodymium magnets can demagnetize at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

The magnet coating is made of nickel, so be cautious 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.

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
