Pros and cons of Nd2Fe14B magnets.
Benefits
- Their strength is maintained, and after around ten years it decreases only by ~1% (according to research),
- Magnets perfectly protect themselves against demagnetization caused by external fields,
- Thanks to the glossy finish, the coating of Ni-Cu-Ni, gold-plated, or silver gives an visually attractive appearance,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of accurate forming and modifying to atypical conditions,
- Fundamental importance in high-tech industry – they find application in computer drives, electromotive mechanisms, precision medical tools, and other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated forms.
- Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these magnets can complicate diagnosis medical after entering the body.
- Due to expensive raw materials, their price is relatively high,
Lifting parameters
Maximum lifting capacity of the magnet – what contributes to it?
- with the contact of a sheet made of special test steel, ensuring maximum field concentration
- whose thickness equals approx. 10 mm
- with an polished touching surface
- under conditions of ideal adhesion (surface-to-surface)
- under vertical force direction (90-degree angle)
- at conditions approx. 20°C
Lifting capacity in practice – influencing factors
- Gap (betwixt the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel type – low-carbon steel attracts best. Alloy steels lower magnetic properties and holding force.
- Plate texture – smooth surfaces ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Thermal factor – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
No play value
These products are not toys. Eating multiple magnets may result in them attracting across intestines, which constitutes a direct threat to life and necessitates immediate surgery.
Protect data
Do not bring magnets near a wallet, computer, or screen. The magnetism can destroy these devices and wipe information from cards.
Respect the power
Handle with care. Rare earth magnets attract from a distance and snap with massive power, often faster than you can react.
Metal Allergy
A percentage of the population suffer from a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact might lead to an allergic reaction. We recommend use protective gloves.
Magnetic interference
Navigation devices and mobile phones are highly sensitive to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.
Magnet fragility
NdFeB magnets are sintered ceramics, meaning they are very brittle. Collision of two magnets leads to them breaking into shards.
Power loss in heat
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.
Flammability
Powder produced during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Crushing risk
Risk of injury: The attraction force is so great that it can result in hematomas, crushing, and even bone fractures. Use thick gloves.
Life threat
Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
