Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They do not lose strength, even over nearly ten years – the decrease in lifting capacity is only ~1% (based on measurements),
- They do not lose their magnetic properties even under external field action,
- A magnet with a metallic nickel surface has an effective appearance,
- Magnets are characterized by huge magnetic induction on the outer layer,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures approaching 230°C and above...
- Possibility of individual shaping and modifying to atypical requirements,
- Versatile presence in modern industrial fields – they are commonly used in hard drives, brushless drives, medical devices, and complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Limited ability of making nuts in the magnet and complicated shapes - preferred is casing - magnet mounting.
- Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these products are able to be problematic in diagnostics medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Lifting parameters
Highest magnetic holding force – what it depends on?
- with the application of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- whose thickness equals approx. 10 mm
- with a surface cleaned and smooth
- under conditions of ideal adhesion (metal-to-metal)
- during pulling in a direction perpendicular to the mounting surface
- at temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Distance – existence of foreign body (paint, dirt, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Direction of force – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Chemical composition of the base – mild steel gives the best results. Higher carbon content reduce magnetic properties and holding force.
- Surface finish – full contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature influence – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet and the plate reduces the holding force.
H&S for magnets
Pacemakers
For implant holders: Powerful magnets disrupt medical devices. Maintain at least 30 cm distance or ask another person to work with the magnets.
Product not for children
NdFeB magnets are not suitable for play. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which constitutes a critical condition and requires immediate surgery.
Respect the power
Use magnets with awareness. Their immense force can surprise even professionals. Plan your moves and respect their power.
Warning for allergy sufferers
Some people suffer from a hypersensitivity to nickel, which is the standard coating for neodymium magnets. Frequent touching can result in skin redness. We suggest use protective gloves.
Cards and drives
Equipment safety: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, timepieces).
Fire risk
Powder generated during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Bone fractures
Mind your fingers. Two large magnets will snap together immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Heat warning
Control the heat. Exposing the magnet to high heat will permanently weaken its properties and strength.
Fragile material
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Magnetic interference
Be aware: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a separation from your mobile, device, and navigation systems.
