Frequently asked questions

How much will a magnetic holder hold in practice?
The catalogue value assumes full contact with smooth steel at least 10 mm thick and a perpendicular pull. Thinner sheet, paint, rust and surface irregularities reduce it considerably: on 1 mm sheet about half remains. Lifting and vertical mounting call for an additional safety margin.
Will a holder work on stainless steel?
Not on austenitic grades 304 and 316 — they are effectively non-magnetic. It will not work on aluminium, copper or brass either. Those materials need a mechanical gripper.
Which coating for which conditions?
Nickel-copper-nickel (NiCuNi) is the standard and covers most applications. Epoxy is used for damp environments and outdoor work, zinc is sufficient for dry interiors. Holders in a steel housing or in rubber also protect the magnet against impact.

Channel holders are some of the most efficient mounting magnets, built based on a steel U-profile (trough). They are widely used in industry for fixing guards, flaps, doors, and in robot grippers.
Mounting is done using countersunk head screws, which hide flat in the housing. Hole spacing allows secure fixing even in difficult conditions.
Thanks to the short-circuiting of the magnetic field by steel side walls, holding force is concentrated and very large. This force is available with direct contact with metal over the entire surface.
Magnets are shielded on three sides by steel, increasing their lifespan and crack resistance. Thanks to solid construction, these holders do not crack as easily as bare neodymium plates.
The product is intended mainly for indoor use (dry rooms). With constant contact with water, corrosion may appear, so we do not recommend them for work in rain without additional protection.

Strengths and weaknesses of neodymium magnets.

Advantages

In addition to their pulling strength, neodymium magnets provide the following advantages:
  • They retain magnetic properties for nearly 10 years – the loss is just ~1% (in theory),
  • They retain their magnetic properties even under strong external field,
  • Thanks to the metallic finish, the coating of Ni-Cu-Ni, gold, or silver-plated gives an clean appearance,
  • They feature high magnetic induction at the operating surface, which increases their power,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
  • Possibility of accurate machining as well as adjusting to precise requirements,
  • Key role in electronics industry – they serve a role in HDD drives, drive modules, diagnostic systems, and modern systems.
  • Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Disadvantages

Drawbacks and weaknesses of neodymium magnets and proposals for their use:
  • They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
  • We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
  • When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
  • We suggest cover - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated forms.
  • Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum magnetic pulling force – what it depends on?

The lifting capacity listed is a result of laboratory testing performed under standard conditions:
  • using a base made of low-carbon steel, acting as a magnetic yoke
  • with a thickness of at least 10 mm
  • characterized by even structure
  • under conditions of gap-free contact (metal-to-metal)
  • under perpendicular application of breakaway force (90-degree angle)
  • at temperature approx. 20 degrees Celsius

What influences lifting capacity in practice

Please note that the application force will differ influenced by elements below, in order of importance:
  • Distance – existence of any layer (paint, tape, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Angle of force application – maximum parameter is obtained only during perpendicular pulling. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
  • Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
  • Material composition – not every steel attracts identically. Alloy additives worsen the attraction effect.
  • Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
  • Thermal environment – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet and the plate lowers the holding force.

Safety rules for work with NdFeB magnets
Precision electronics

GPS units and smartphones are extremely sensitive to magnetism. Direct contact with a strong magnet can permanently damage the sensors in your phone.

Physical harm

Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing anything in their path. Be careful!

Machining danger

Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Safe operation

Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.

Implant safety

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.

Material brittleness

Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.

Metal Allergy

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.

Magnetic media

Device Safety: Strong magnets can damage payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).

Maximum temperature

Watch the temperature. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.

No play value

Only for adults. Small elements pose a choking risk, leading to severe trauma. Keep out of reach of children and animals.
