Frequently asked questions

Do you make magnets to order?
Yes. We make sizes and shapes outside the catalogue, in grades from N27 to N55 and in high-temperature versions. Lead time depends on the shape and batch size — for rings it is 25–35 days.
Which coating should I choose?
NiCuNi is the standard and covers most applications. Zinc is cheaper and suits dry interiors, epoxy suits damp conditions and outdoor use, gold is chosen where appearance matters. An uncoated magnet corrodes in humid air within a few hours.
Will I receive documentation with my order?
Yes. We issue a REACH statement for the article, a declaration of conformity for the packaging under PPWR, and a certificate of measured magnetic parameters. Documents are issued on request, for a specific article or order number.

This category contains replaceable tips, adapters, and fasteners for magnets. We offer, among others: various types of hooks, eyelet holders, mounting plates for magnets, and rubber anti-slip caps. Thanks to these additions, you can adapt any magnetic holder to your individual needs.
The plate serves as a base (armature) to which the magnet will attach. After fixing the plate, you gain a place where the magnet will hold just like on a fridge. It's an ideal solution for closing cabinets, hanging tools, or mounting smoke detectors.
Tips fit sockets with thread M3, M4, M5, M6, M8, M10, M12, etc. It is important to select a hook or screw with the same thread diameter as the socket in the magnet. Most elements are protected against rust by galvanic zinc.
The cap increases friction (coefficient of friction), preventing the magnet from sliding down a vertical wall. They are ideal when you want to attach a magnet to car paint, a fridge, or furniture. However, remember that rubber creates a distance, which slightly reduces perpendicular lifting force.
Yes, as a direct importer, we serve both retail and wholesale customers. For larger orders, we offer attractive discounts and individual quotes. We guarantee continuity of supply and high quality of fasteners.

Strengths and weaknesses of neodymium magnets.

Strengths

Besides their high retention, neodymium magnets are valued for these benefits:
  • Their power is durable, and after around 10 years it drops only by ~1% (according to research),
  • They show high resistance to demagnetization induced by external field influence,
  • By covering with a shiny coating of nickel, the element acquires an aesthetic look,
  • Neodymium magnets ensure maximum magnetic induction on a their surface, which allows for strong attraction,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
  • Thanks to freedom in designing and the capacity to customize to individual projects,
  • Significant place in electronics industry – they are commonly used in mass storage devices, electromotive mechanisms, medical devices, and modern systems.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

Disadvantages of NdFeB magnets:
  • At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
  • We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 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 stable to moisture, when using outdoors
  • Due to limitations in producing nuts and complicated forms in magnets, we propose using casing - magnetic holder.
  • Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Furthermore, small components of these magnets are able to complicate diagnosis medical when they are in the body.
  • Due to expensive raw materials, their price exceeds standard values,

Holding force characteristics

Maximum holding power of the magnet – what affects it?

Information about lifting capacity was defined for ideal contact conditions, taking into account:
  • using a sheet made of mild steel, functioning as a circuit closing element
  • possessing a massiveness of min. 10 mm to ensure full flux closure
  • characterized by smoothness
  • under conditions of gap-free contact (surface-to-surface)
  • during detachment in a direction vertical to the plane
  • at standard ambient temperature

Determinants of lifting force in real conditions

It is worth knowing that the application force will differ influenced by the following factors, in order of importance:
  • Gap (between the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, rust or debris).
  • Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
  • Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
  • Material composition – different alloys reacts the same. Alloy additives worsen the attraction effect.
  • Plate texture – smooth surfaces ensure maximum contact, which improves force. Uneven metal weaken the grip.
  • Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity was measured using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.

Warnings
No play value

Product intended for adults. Tiny parts can be swallowed, causing serious injuries. Store away from kids and pets.

Finger safety

Large magnets can crush fingers instantly. Never place your hand betwixt two attracting surfaces.

Data carriers

Powerful magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.

Risk of cracking

Protect your eyes. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.

Medical implants

Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.

Powerful field

Handle magnets consciously. Their huge power can surprise even experienced users. Be vigilant and do not underestimate their power.

Dust explosion hazard

Powder produced during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Metal Allergy

Certain individuals suffer from a contact allergy to Ni, which is the standard coating for NdFeB magnets. Prolonged contact can result in an allergic reaction. We recommend use protective gloves.

Heat warning

Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.

Precision electronics

Note: rare earth magnets produce a field that confuses precision electronics. Maintain a safe distance from your phone, tablet, and GPS.
