Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They do not lose power, even during nearly ten years – the drop in power is only ~1% (theoretically),
- They maintain their magnetic properties even under external field action,
- By covering with a lustrous coating of nickel, the element gains an aesthetic look,
- They show 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 shape) even at temperatures up to 230°C and higher...
- Possibility of precise creating and adapting to concrete requirements,
- Versatile presence in innovative solutions – they are utilized in HDD drives, brushless drives, precision medical tools, also other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- We suggest casing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what affects it?
- with the contact of a yoke made of low-carbon steel, ensuring full magnetic saturation
- with a thickness minimum 10 mm
- with an polished touching surface
- with zero gap (no impurities)
- during detachment in a direction vertical to the plane
- at conditions approx. 20°C
Determinants of practical lifting force of a magnet
- Clearance – existence of foreign body (rust, tape, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Angle of force application – highest force is available only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
- Surface finish – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, reducing force.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the load capacity.
H&S for magnets
Bone fractures
Danger of trauma: The attraction force is so immense that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.
Caution required
Handle with care. Rare earth magnets attract from a long distance and connect with massive power, often quicker than you can react.
Material brittleness
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
ICD Warning
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Swallowing risk
Product intended for adults. Small elements can be swallowed, leading to serious injuries. Store out of reach of kids and pets.
Safe distance
Do not bring magnets near a wallet, computer, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Thermal limits
Keep cool. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
GPS Danger
A strong magnetic field disrupts the operation of compasses in phones and GPS navigation. Do not bring magnets close to a smartphone to avoid breaking the sensors.
Fire warning
Fire warning: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.
Allergic reactions
Nickel alert: The nickel-copper-nickel coating contains nickel. If skin irritation happens, cease handling magnets and use protective gear.
