Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They have unchanged lifting capacity, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
- Magnets perfectly defend themselves against loss of magnetization caused by foreign field sources,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to look better,
- They show high magnetic induction at the operating surface, making them more effective,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of precise machining and optimizing to atypical conditions,
- Key role in innovative solutions – they are used in HDD drives, motor assemblies, medical devices, and other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets experience a drop in power. 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 while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of producing nuts in the magnet and complex forms - preferred is cover - magnet mounting.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small elements of these devices are able to be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
- possessing a thickness of at least 10 mm to avoid saturation
- characterized by even structure
- without any air gap between the magnet and steel
- under perpendicular force vector (90-degree angle)
- at temperature room level
Lifting capacity in practice – influencing factors
- Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Load vector – maximum parameter is reached only during perpendicular pulling. The shear force of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin sheet does not accept the full field, causing part of the power to be escaped to the other side.
- Steel grade – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
- Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.
Safe handling of NdFeB magnets
No play value
NdFeB magnets are not toys. Eating a few magnets may result in them connecting inside the digestive tract, which constitutes a severe health hazard and requires urgent medical intervention.
Shattering risk
NdFeB magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets will cause them breaking into small pieces.
Permanent damage
Do not overheat. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Handling guide
Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Physical harm
Risk of injury: The attraction force is so great that it can result in hematomas, pinching, and broken bones. Use thick gloves.
Fire risk
Drilling and cutting of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Implant safety
Individuals with a pacemaker have to keep an large gap from magnets. The magnetism can stop the operation of the life-saving device.
GPS Danger
Navigation devices and mobile phones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can decalibrate the sensors in your phone.
Cards and drives
Avoid bringing magnets close to a purse, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.
Nickel coating and allergies
Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation happens, immediately stop handling magnets and wear gloves.
