Pros as well as cons of Nd2Fe14B magnets.
Advantages
- They retain attractive force for nearly ten years – the drop is just ~1% (based on simulations),
- Neodymium magnets prove to be highly resistant to loss of magnetic properties caused by external interference,
- In other words, due to the smooth surface of silver, the element becomes visually attractive,
- The surface of neodymium magnets generates a powerful 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 form) at temperatures up to 230°C and above...
- In view of the ability of accurate molding and customization to unique solutions, neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of possible applications,
- Universal use in advanced technology sectors – they find application in data components, motor assemblies, diagnostic systems, as well as industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of creating nuts in the magnet and complex shapes - recommended is casing - mounting mechanism.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these magnets can disrupt the diagnostic process medical in case of swallowing.
- Due to expensive raw materials, their price is higher than average,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what affects it?
- using a base made of mild steel, functioning as a circuit closing element
- possessing a thickness of minimum 10 mm to avoid saturation
- with a surface perfectly flat
- under conditions of ideal adhesion (metal-to-metal)
- under axial force vector (90-degree angle)
- at room temperature
Lifting capacity in real conditions – factors
- Clearance – existence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Element 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 finish – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Heat – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was measured with the use of a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.
Dust is flammable
Dust generated during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
No play value
Product intended for adults. Small elements pose a choking risk, leading to severe trauma. Keep away from kids and pets.
Beware of splinters
Watch out for shards. Magnets can explode upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.
GPS Danger
Be aware: neodymium magnets generate a field that disrupts precision electronics. Maintain a separation from your phone, device, and GPS.
Nickel coating and allergies
A percentage of the population suffer from a hypersensitivity to nickel, which is the typical protective layer for neodymium magnets. Extended handling can result in skin redness. We strongly advise use safety gloves.
Electronic devices
Equipment safety: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, timepieces).
Pinching danger
Big blocks can break fingers in a fraction of a second. Under no circumstances put your hand between two strong magnets.
Heat warning
Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. Damage is permanent.
Do not underestimate power
Handle with care. Rare earth magnets act from a distance and snap with massive power, often quicker than you can react.
ICD Warning
Individuals with a pacemaker have to keep an safe separation from magnets. The magnetic field can disrupt the functioning of the life-saving device.
