Other offers

In this category, we offer a wide selection of complementary elements for magnetic holders. We offer, among others: various types of hooks, eye bolts (shackles), mounting plates for magnets, and rubber covers. These are essential elements to fully utilize the potential of neodymium magnets in practice.
Thanks to steel plates, you can create a magnetic point on wood, plastic, glass, or wall. 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. Before purchase, check the thread size in your magnetic holder (it is given in the description). Most elements are protected against rust by galvanic zinc.
Covers made of thin rubber protect delicate surfaces from scratching by a metal magnet. Use them wherever direct metal contact could damage the surface. An additional layer of rubber weakens attraction slightly but drastically increases shear force (sliding resistance).
Yes, as a direct importer, we serve both retail and wholesale customers. Contact us to get a wholesale offer for hooks and holders. We guarantee continuity of supply and high quality of fasteners.

Advantages and disadvantages of NdFeB magnets.

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

  • They retain full power for around ten years – the loss is just ~1% (in theory),
  • Neodymium magnets are distinguished by highly resistant to magnetic field loss caused by external field sources,
  • A magnet with a metallic gold surface looks better,
  • Neodymium magnets deliver maximum magnetic induction on a small surface, which increases force concentration,
  • 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 custom shaping and adapting to atypical needs,
  • Fundamental importance in modern technologies – they serve a role in magnetic memories, motor assemblies, precision medical tools, also modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in compact constructions

Disadvantages of neodymium magnets:

  • At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
  • They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using cover - magnetic holder.
  • Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Additionally, tiny parts of these products are able to complicate diagnosis medical in case of swallowing.
  • With budget limitations the cost of neodymium magnets is economically unviable,

Optimal lifting capacity of a neodymium magnetwhat it depends on?

The load parameter shown refers to the maximum value, measured under optimal environment, meaning:

  • on a plate made of mild steel, perfectly concentrating the magnetic field
  • possessing a thickness of min. 10 mm to avoid saturation
  • characterized by smoothness
  • with direct contact (no impurities)
  • under axial force vector (90-degree angle)
  • in stable room temperature

Key elements affecting lifting force

Holding efficiency is influenced by working environment parameters, such as (from most important):

  • Gap (betwixt the magnet and the metal), since even a tiny clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
  • Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of nominal force).
  • Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
  • Chemical composition of the base – mild steel attracts best. Alloy admixtures decrease magnetic permeability and holding force.
  • Smoothness – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
  • Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.

* Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance {between} the magnet and the plate decreases the lifting capacity.

Safety rules for work with neodymium magnets

Phone sensors

A strong magnetic field negatively affects the operation of magnetometers in phones and GPS navigation. Do not bring magnets close to a smartphone to avoid damaging the sensors.

Serious injuries

Pinching hazard: The pulling power is so great that it can cause hematomas, crushing, and even bone fractures. Protective gloves are recommended.

Conscious usage

Exercise caution. Rare earth magnets attract from a distance and connect with massive power, often quicker than you can move away.

Material brittleness

NdFeB magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets will cause them cracking into small pieces.

Flammability

Drilling and cutting of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Avoid contact if allergic

Some people suffer from a sensitization to nickel, which is the common plating for neodymium magnets. Extended handling may cause dermatitis. We strongly advise use safety gloves.

Power loss in heat

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

Keep away from computers

Intense magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.

No play value

Absolutely keep magnets away from children. Choking hazard is significant, and the consequences of magnets clamping inside the body are life-threatening.

Medical interference

Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
