Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- Their strength is maintained, and after approximately 10 years it decreases only by ~1% (according to research),
- They possess excellent resistance to weakening of magnetic properties due to external magnetic sources,
- In other words, due to the shiny surface of gold, the element is aesthetically pleasing,
- Magnets have excellent magnetic induction on the surface,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
- Possibility of individual shaping and modifying to complex conditions,
- Key role in innovative solutions – they find application in mass storage devices, drive modules, medical equipment, as well as modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Cons
- To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited possibility of making threads in the magnet and complicated shapes - recommended is cover - mounting mechanism.
- Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Additionally, small elements of these products are able to be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- using a plate made of mild steel, functioning as a ideal flux conductor
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with a plane perfectly flat
- with total lack of distance (without paint)
- for force applied at a right angle (in the magnet axis)
- in stable room temperature
Lifting capacity in real conditions – factors
- Gap (betwixt the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Direction of force – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin plate does not accept the full field, causing part of the flux to be lost into the air.
- Metal type – different alloys attracts identically. High carbon content weaken the attraction effect.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet’s surface and the plate reduces the holding force.
H&S for magnets
Product not for children
These products are not intended for children. Swallowing several magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and requires immediate surgery.
Allergy Warning
Certain individuals have a hypersensitivity to Ni, which is the standard coating for neodymium magnets. Prolonged contact may cause an allergic reaction. We recommend wear protective gloves.
Maximum temperature
Do not overheat. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
Compass and GPS
Note: rare earth magnets generate a field that disrupts precision electronics. Keep a separation from your mobile, device, and navigation systems.
Powerful field
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Medical implants
Warning for patients: Powerful magnets affect electronics. Keep at least 30 cm distance or request help to work with the magnets.
Bone fractures
Risk of injury: The attraction force is so great that it can cause hematomas, crushing, and even bone fractures. Protective gloves are recommended.
Material brittleness
Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Wear goggles.
Machining danger
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Electronic hazard
Data protection: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).
