The steel cup acts as an armature, concentrating the magnetic flux and increasing capacity even several times. Moreover, the metal housing protects the brittle neodymium magnet from cracking upon impact. The bushing with internal thread allows easy screwing of any element (bolt, hook, handle).
The most important rule is choosing the appropriate length of the screw being screwed in. Neodymium magnets are brittle, and direct pressure from a screw can cause them to crack or detach. It is worth securing the thread with thread glue if the connection is to be durable and resistant to vibrations.
They are indispensable when building exhibition stands and shop displays (POS systems). They serve as a base for hooks, cable holders, organizers, and lighting systems. Ideal for fixing lighting on machine tools and welding tables.
This value applies to perfect adherence with the entire magnet surface. With thin sheets (e.g., car body, fridge casing), the force will be much smaller because steel cannot absorb the entire magnetic field. We always recommend choosing a magnet with power reserve, especially if the surface is not ideal.
Standard coating effectively protects against moisture in indoor conditions. However, these are not fully stainless products and may corrode with constant contact with water. The neodymium magnet itself inside is also nickel-plated.

Advantages and disadvantages of neodymium magnets.

Advantages

Besides their stability, neodymium magnets are valued for these benefits:
  • They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
  • They maintain their magnetic properties even under external field action,
  • By applying a smooth layer of gold, the element has an elegant look,
  • Magnetic induction on the working layer of the magnet remains impressive,
  • Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures reaching 230°C and above...
  • Considering the ability of free forming and adaptation to individualized needs, magnetic components can be produced in a wide range of forms and dimensions, which increases their versatility,
  • Universal use in modern industrial fields – they serve a role in computer drives, electric motors, medical equipment, also technologically advanced constructions.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

Characteristics of disadvantages of neodymium magnets and ways of using them
  • At very strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
  • We recommend casing - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated forms.
  • Health risk to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Additionally, small elements of these magnets are able to be problematic in diagnostics medical after entering the body.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Maximum magnetic pulling force – what affects it?

The lifting capacity listed is a theoretical maximum value executed under specific, ideal conditions:
  • using a base made of high-permeability steel, acting as a magnetic yoke
  • with a thickness minimum 10 mm
  • characterized by smoothness
  • without any air gap between the magnet and steel
  • during pulling in a direction vertical to the plane
  • at ambient temperature room level

Practical aspects of lifting capacity – factors

Bear in mind that the working load may be lower depending on the following factors, starting with the most relevant:
  • Gap (betwixt the magnet and the plate), as even a very small distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, rust or debris).
  • Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
  • Steel thickness – too thin steel does not close the flux, causing part of the flux to be lost to the other side.
  • Material type – ideal substrate is pure iron steel. Stainless steels may attract less.
  • Surface finish – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Thermal environment – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.

Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate lowers the holding force.

H&S for magnets
Allergic reactions

Nickel alert: The nickel-copper-nickel coating contains nickel. If redness happens, immediately stop handling magnets and use protective gear.

Do not underestimate power

Handle magnets consciously. Their immense force can shock even professionals. Be vigilant and do not underestimate their force.

Material brittleness

Protect your eyes. Magnets can fracture upon violent connection, launching shards into the air. Eye protection is mandatory.

Serious injuries

Big blocks can break fingers instantly. Under no circumstances put your hand between two attracting surfaces.

Mechanical processing

Powder produced during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.

Demagnetization risk

Control the heat. Exposing the magnet to high heat will destroy its properties and pulling force.

Phone sensors

Remember: neodymium magnets generate a field that interferes with precision electronics. Keep a separation from your mobile, tablet, and GPS.

Do not give to children

NdFeB magnets are not intended for children. Eating a few magnets may result in them pinching intestinal walls, which poses a critical condition and requires urgent medical intervention.

Electronic devices

Powerful magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.

ICD Warning

People with a pacemaker have to maintain an large gap from magnets. The magnetic field can stop the functioning of the life-saving device.
