Other offers
Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- They feature excellent resistance to magnetism drop when exposed to external magnetic sources,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- In view of the ability of flexible forming and customization to custom solutions, NdFeB magnets can be modeled in a broad palette of forms and dimensions, which expands the range of possible applications,
- Fundamental importance in future technologies – they are utilized in magnetic memories, motor assemblies, medical devices, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in compact constructions
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- We recommend cover - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Additionally, small components of these magnets are able to be problematic in diagnostics medical when they are in the body.
- Due to expensive raw materials, their price exceeds standard values,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- on a base made of structural steel, effectively closing the magnetic field
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an polished contact surface
- under conditions of gap-free contact (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Clearance – existence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Load vector – maximum parameter is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Metal type – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
- Plate texture – ground elements ensure maximum contact, which improves field saturation. Uneven metal weaken the grip.
- Thermal environment – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Precautions when working with neodymium magnets
Power loss in heat
Monitor thermal conditions. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.
Safe distance
Data protection: Strong magnets can damage payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
No play value
Only for adults. Tiny parts can be swallowed, leading to severe trauma. Keep out of reach of children and animals.
Sensitization to coating
It is widely known that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, refrain from direct skin contact or opt for coated magnets.
Pinching danger
Large magnets can crush fingers instantly. Under no circumstances place your hand betwixt two strong magnets.
Caution required
Handle with care. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can move away.
Health Danger
Health Alert: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
GPS Danger
Note: rare earth magnets generate a field that confuses precision electronics. Keep a separation from your mobile, tablet, and navigation systems.
Eye protection
Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Do not drill into magnets
Fire hazard: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.
