Shopping tips
Moreover, even though neodymium is part of the strongest magnets, they are prone to corrosion in humid environments. Therefore, they are coated with a thin layer of silver 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 care 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. It is advisable to avoid their use 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 guaranteed.
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 shield them from environmental factors and extend their lifespan. High temperatures exceeding 130°C can result in a deterioration of their magnetic strength, 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 environment containing hydrogen, as they may forfeit their magnetic properties.
Advantages and disadvantages of neodymium magnets NdFeB.
Besides their durability, neodymium magnets are valued for these benefits:
- They retain their full power for nearly 10 years – the loss is just ~1% (according to analyses),
- Their ability to resist magnetic interference from external fields is among the best,
- Because of the lustrous layer of gold, the component looks high-end,
- They possess intense magnetic force measurable at the magnet’s surface,
- With the right combination of materials, they reach significant thermal stability, enabling operation at or above 230°C (depending on the structure),
- The ability for precise shaping as well as customization to custom needs – neodymium magnets can be manufactured in multiple variants of geometries, which amplifies their functionality across industries,
- Important function in modern technologies – they are utilized in HDDs, electric drives, medical equipment and sophisticated instruments,
- Thanks to their power density, small magnets offer high magnetic performance, while occupying minimal space,
Disadvantages of magnetic elements:
- They are fragile when subjected to a strong impact. If the magnets are exposed to shocks, we recommend in a metal holder. The steel housing, in the form of a holder, protects the magnet from cracks and enhances its overall robustness,
- High temperatures may significantly reduce the magnetic power 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,
- Due to corrosion risk in humid conditions, it is wise to use sealed magnets made of plastic for outdoor use,
- Limited ability to create precision features in the magnet – the use of a mechanical support is recommended,
- Potential hazard from tiny pieces may arise, especially if swallowed, which is significant in the health of young users. Furthermore, tiny components from these products might complicate medical imaging once in the system,
- Due to a complex production process, their cost is relatively high,
Be Cautious with Neodymium Magnets
Neodymium magnets are the strongest magnets ever created, and their strength can shock you.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional damage to the magnets.
Dust and powder from neodymium magnets are 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.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
If have a finger between or on the path of attracting magnets, there may be a large cut or even a fracture.
The magnet coating is made of nickel, so be cautious if you have an allergy.
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.
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.
It is important to keep neodymium magnets away from youngest children.
Remember that neodymium magnets are not toys. Be cautious and make sure no child plays 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.
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.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
Magnetic fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Magnets made of neodymium are delicate and can easily crack and shatter.
Magnets made of neodymium are fragile as well as will crack if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.
Neodymium magnets can demagnetize at high temperatures.
Although magnets are generally resilient, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Safety precautions!
