Special coating protects oxide, Cerakote coatings, and other finishes from destruction. The pistol holds stably, securely, and does not rotate on the holder.
Holding force is sufficient for the weapon not to fall even during shocks (e.g., in a car). For long guns (rifle, shotgun), we recommend using two holders (one for the barrel/handguard, the other for the stock/chamber).
Thanks to the flat profile, it is easy to hide and discreetly mount. You can screw it to wood, metal, plastic, or furniture board.
The holder works with any weapon made of ferromagnetic metal (steel), which covers 99% of the market. The shape of the holder allows fitting to various slide profiles, including flat and rounded.
The holder serves for safe storage or transport, however, the user must strictly comply with applicable regulations. We recommend complying with the Weapons and Ammunition Act and common sense.

Pros as well as cons of rare earth magnets.

Strengths

In addition to their long-term stability, neodymium magnets provide the following advantages:
  • They do not lose magnetism, even over nearly 10 years – the drop in strength is only ~1% (theoretically),
  • They do not lose their magnetic properties even under strong external field,
  • Thanks to the metallic finish, the surface of nickel, gold-plated, or silver-plated gives an clean appearance,
  • The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
  • Possibility of individual machining and adjusting to individual requirements,
  • Huge importance in future technologies – they are commonly used in computer drives, electric motors, diagnostic systems, as well as modern systems.
  • Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Disadvantages

Problematic aspects of neodymium magnets and ways of using them
  • Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
  • We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
  • They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • We recommend casing - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated shapes.
  • Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Furthermore, small elements of these devices can disrupt the diagnostic process medical when they are in the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum magnetic pulling force – what contributes to it?

Magnet power is the result of a measurement for optimal configuration, assuming:
  • with the application of a sheet made of special test steel, ensuring full magnetic saturation
  • with a thickness of at least 10 mm
  • with an ground touching surface
  • with direct contact (no coatings)
  • under axial application of breakaway force (90-degree angle)
  • at standard ambient temperature

Lifting capacity in practice – influencing factors

In real-world applications, the real power depends on many variables, ranked from most significant:
  • Gap (betwixt the magnet and the metal), because even a very small distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
  • Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
  • Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
  • Material type – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
  • Surface structure – the more even the surface, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
  • Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate lowers the holding force.

H&S for magnets
Do not underestimate power

Handle magnets with awareness. Their huge power can surprise even experienced users. Stay alert and do not underestimate their power.

Medical implants

Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Risk of cracking

Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Electronic devices

Intense magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Stay away of at least 10 cm.

Magnetic interference

Navigation devices and smartphones are extremely sensitive to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.

Fire warning

Powder generated during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Crushing risk

Watch your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!

Maximum temperature

Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.

This is not a toy

NdFeB magnets are not toys. Eating several magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and necessitates immediate surgery.

Metal Allergy

Some people suffer from a sensitization to Ni, which is the typical protective layer for neodymium magnets. Frequent touching might lead to dermatitis. It is best to use protective gloves.
