Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
- They have excellent resistance to magnetism drop as a result of external fields,
- The use of an refined coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Considering the potential of precise shaping and adaptation to specialized requirements, magnetic components can be produced in a variety of forms and dimensions, which makes them more universal,
- Versatile presence in electronics industry – they are used in mass storage devices, motor assemblies, diagnostic systems, as well as other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets lose their power 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 durability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complicated shapes in magnets, we propose using cover - magnetic mount.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Additionally, tiny parts of these magnets are able to disrupt the diagnostic process medical after entering the body.
- Due to expensive raw materials, their price is relatively high,
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- using a sheet made of low-carbon steel, acting as a ideal flux conductor
- whose thickness is min. 10 mm
- with a plane perfectly flat
- without any insulating layer between the magnet and steel
- under perpendicular force vector (90-degree angle)
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Clearance – the presence of any layer (paint, dirt, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Metal type – different alloys attracts identically. Alloy additives worsen the attraction effect.
- Plate texture – ground elements ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was measured by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate reduces the load capacity.
Warnings
Life threat
For implant holders: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or request help to handle the magnets.
Metal Allergy
Some people suffer from a sensitization to nickel, which is the common plating for neodymium magnets. Frequent touching might lead to skin redness. We strongly advise use safety gloves.
Data carriers
Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).
Crushing risk
Large magnets can crush fingers in a fraction of a second. Do not place your hand betwixt two attracting surfaces.
Flammability
Powder generated during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Conscious usage
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Do not give to children
Strictly keep magnets away from children. Choking hazard is significant, and the consequences of magnets clamping inside the body are tragic.
Magnetic interference
GPS units and mobile phones are highly sensitive to magnetism. Close proximity with a strong magnet can ruin the sensors in your phone.
Shattering risk
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Operating temperature
Keep cool. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
