Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- They have stable power, and over more than 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They have excellent resistance to magnetism drop as a result of external magnetic sources,
- A magnet with a shiny silver surface has an effective appearance,
- They feature high magnetic induction at the operating surface, making them more effective,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Considering the ability of free molding and adaptation to individualized requirements, magnetic components can be produced in a wide range of geometric configurations, which makes them more universal,
- Key role in advanced technology sectors – they are utilized in hard drives, electric drive systems, medical devices, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in miniature devices
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- 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 as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- We recommend cover - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these magnets can complicate diagnosis medical in case of swallowing.
- With mass production the cost of neodymium magnets is economically unviable,
Pull force analysis
Highest magnetic holding force – what it depends on?
- with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
- possessing a massiveness of at least 10 mm to avoid saturation
- with an ideally smooth touching surface
- without the slightest insulating layer between the magnet and steel
- under perpendicular application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Space between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Plate material – low-carbon steel attracts best. Alloy admixtures lower magnetic properties and holding force.
- Plate texture – ground elements ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
H&S for magnets
Fragile material
Neodymium magnets are sintered ceramics, which means they are very brittle. Collision of two magnets leads to them shattering into shards.
Keep away from electronics
A strong magnetic field disrupts the operation of magnetometers in phones and GPS navigation. Maintain magnets close to a device to avoid breaking the sensors.
ICD Warning
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Do not underestimate power
Handle magnets consciously. Their immense force can surprise even experienced users. Stay alert and respect their force.
Finger safety
Big blocks can break fingers instantly. Do not put your hand between two attracting surfaces.
Protect data
Do not bring magnets close to a purse, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.
Allergy Warning
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, cease working with magnets and wear gloves.
Heat warning
Keep cool. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Flammability
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Adults only
Adult use only. Small elements pose a choking risk, causing severe trauma. Store out of reach of kids and pets.
