Pros and cons of Nd2Fe14B magnets.
Benefits
- They do not lose power, even over approximately ten years – the reduction in strength is only ~1% (according to tests),
- They feature excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
- In other words, due to the shiny surface of gold, the element gains a professional look,
- Magnets have very high magnetic induction on the outer layer,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to flexibility in forming and the ability to adapt to client solutions,
- Fundamental importance in electronics industry – they find application in data components, motor assemblies, medical equipment, as well as multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complicated forms in magnets, we propose using cover - magnetic mount.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these magnets are able to be problematic in diagnostics medical after entering the body.
- Due to complex production process, their price is relatively high,
Lifting parameters
Best holding force of the magnet in ideal parameters – what contributes to it?
- with the application of a sheet made of special test steel, guaranteeing maximum field concentration
- with a thickness minimum 10 mm
- with an polished contact surface
- without any air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at temperature room level
Practical lifting capacity: influencing factors
- Clearance – the presence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Stainless steels may attract less.
- Surface structure – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the holding force.
Safety rules for work with neodymium magnets
GPS Danger
GPS units and smartphones are highly susceptible to magnetic fields. Direct contact with a strong magnet can permanently damage the sensors in your phone.
Warning for allergy sufferers
It is widely known that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, refrain from touching magnets with bare hands and choose encased magnets.
Swallowing risk
Neodymium magnets are not suitable for play. Accidental ingestion of a few magnets can lead to them attracting across intestines, which constitutes a critical condition and necessitates urgent medical intervention.
Combustion hazard
Powder produced during grinding of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Operating temperature
Do not overheat. NdFeB magnets are sensitive to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Data carriers
Do not bring magnets near a purse, laptop, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Magnet fragility
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
Medical interference
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Pinching danger
Large magnets can smash fingers in a fraction of a second. Do not place your hand betwixt two strong magnets.
Safe operation
Handle magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and respect their force.
