We naturally offer graduated prices and discounts for bulk orders. We only supply corporate customers - enquiries received via our homepage will be checked individually (select products and save them in the watch list, specifying the quantities, then start a price enquiry). Alternatively, you can also contact our sales staff directly

We offer our corporate customers framework agreements and long-term supply agreements with special conditions. We would be happy to discuss individual agreements with you that are tailored to your specific requirements.

Development, design, sales and our customer support take place in Germany (Hardt site). We obtain the raw magnets (the magnetic material) from selected partners in China. Final production, assembly and quality control are carried out exclusively here in the Black Forest in order to guarantee our high quality standards.

We are in close dialogue with our suppliers and are working with our local consultants to overcome the exceptional situation and create solutions. We receive deliveries from China on a weekly basis and are doing our best to minimise the impact of export restrictions on our customers. We are also using the EU's tool to speed up export authorisations. Tip: Ordering early helps us to secure your supply.

Due to the current situation with export restrictions and increased customs controls, there may be longer waiting times. Unfortunately, the processing times are not transparent and can vary. Suppliers only register a delivery for dispatch once an export licence has been issued. The customs inspection takes between 8-10 weeks, while the export licence process can take around 12 weeks - as the two processes unfortunately do not run in parallel, this adds up to over 20 weeks. We do our best to keep delivery times as short as possible and will inform you of any delays if necessary.

We are happy to provide you with information on the origin of the raw materials for our magnets if required. Thanks to our close contacts in China and as a co-initiator of the FairMagnet initiative, we have comprehensive insights into our supply chains and can provide you with detailed information on request.

On our contact page you will find all the important contact persons with their respective responsibilities. A special contact person is also available in this section for our complaints management.

We offer a wide range of magnets and magnet systems for various applications. These include neodymium magnets (particularly strong magnets), ferrite magnets (cost-effective and corrosion-resistant) and samarium-cobalt magnets (ideal for high temperatures). Depending on the type of application, we will advise you on the right magnet material.

At Brugger, we have several stationary high-performance magnetising systems, which are essential for transforming non-magnetic blanks (hard ferrites, neodymium-iron-boron, etc.) into permanent magnets. We can supply our magnet systems with different types of magnetisation. The type of magnetisation, such as axial, sector, multipole or radial, depends on the application and the material. More info in the Bruggerpedia.

The adhesive force specified in the data sheet only applies to vertical pull-off (tensile shear strength 90°). If you load a magnet on a vertical wall, the so-called shear force (displacement force) acts. Depending on the coefficient of friction between the magnet and the surface (steel vs. paint), the actual holding force in the shear direction is often only 15% to 25% of the specified holding force. This is why a magnet holds less on the wall than on the ceiling.

Coatings protect the magnets from environmental influences such as corrosion and abrasion. Each coating has specific advantages:

• Nickel plating (Ni) and galvanising (Zn) offer good corrosion protection.

• Epoxy resin (epoxy) protects against moisture and chemicals.

• Rubber coating (TPE) protects sensitive surfaces from scratches and increases static friction.

• Parylene is a thin, biocompatible layer that offers extreme protection.

Magnets can be used very well outdoors, provided they are appropriately protected. Our rubberised magnet systems are specially designed for outdoor use and offer excellent protection from the elements thanks to their UV-resistant rubber coating. This rubber coating also prevents scratches on sensitive surfaces and increases friction, allowing the magnets to adhere more securely.

We guarantee the consistency and reliability of our magnet systems through comprehensive quality management that accompanies the entire production process. From the procurement of raw materials to production and final assembly, we carry out continuous inspections to ensure the highest quality standards. Our vertical integration enables us to control and optimise all processes internally, which ensures efficient and high-quality production.

We do not rely on manufacturer specifications, but test them ourselves. We measure critical parameters with our in-house measurement technology (e.g. Helmholtz coils, fluxmeters, holding force measuring device). For complex systems in particular, each individual magnet is tested before and after installation.

We do not rely on theoretical calculations, but on empirical tests in our own laboratory. The adhesive force is determined on a calibrated, computer-controlled tensile testing machine. We pull the magnet vertically from a flat ground steel plate. This ensures that our data is precise and reproducible.

Under normal conditions, our permanent magnets retain their magnetisation almost indefinitely. Factors that can lead to a loss of force are extreme heat (above the Curie temperature), strong external opposing fields or hard impacts on certain materials.

Neodymium-iron-boron (NdFeB) magnets are currently the strongest permanent magnets on the market. Samarium-cobalt (SmCo) magnets are often preferred for applications at extremely high temperatures (over 200°C), as they are more temperature-stable, even if they have slightly less force than neodymium. You can find out more in the Bruggerpedia under "Materials".

The main difference lies in their strength and robustness. Neodymium magnets (NdFeB) are considerably stronger for the same size (super magnets), but are more susceptible to corrosion and high temperatures. Ferrite magnets are cheaper, weatherproof and extremely heat-resistant, but have a lower adhesive force.

These abbreviations stand for the magnetic quality (grade), i.e. here the neodymium quality classes and the maximum energy product of a neodymium magnet (in Mega-Gauss-Oersted, MGOe). Put simply: the higher the number, the stronger the magnet is for the same volume. An N52 magnet is currently the strongest commercially available material and is around 35-50% stronger than a standard N35 magnet. We work closely with our customers to identify and source the right magnet material for their specific applications. We consider all available magnet grades and select them according to the specific application requirements.

Yes, we also build magnetic couplings, Halbach arrays and ring gap systems. At BRUGGER, we always have an open ear for special developments in the field of magnets. We do everything we can to understand your individual challenges and develop customised solutions. Our experienced team will support you from the initial idea through to realisation - producing both customised products and prototypes.

No. Our magnet systems and all the coatings we use, including our high-quality parylene coatings, are free from PFAS (perfluorinated and polyfluorinated alkyl substances). We attach great importance to safe and sustainable materials.

Yes, our products are REACH and RoHS compliant. Our magnet systems are labelled on our website with special symbols that indicate their REACH and RoHS conformity.

Magnets themselves are not toxic. However, they can contain chemical components such as nickel, which can cause allergic reactions if they come into direct contact with the skin. There is also a risk of serious health complications if magnets are swallowed, especially by children. Therefore, magnets should always be kept out of the reach of children and handled with care. Magnetic fields can interfere with the function of pacemakers and other medical implants. People with such devices should therefore keep a safe distance from strong magnets.

There is a risk of injury if magnets are handled incorrectly. Therefore, please observe the following important instructions:

• Beware of crushing injuries: The strong attractive forces of magnets can pinch skin and fingers. Magnets also attract each other over large distances - therefore always keep a sufficient distance.

• Risk of splintering: Magnets can shatter into sharp-edged pieces on impact4. Therefore, avoid any impacts or collisions.

• Protection of electronics: Strong magnetic fields can affect or damage electronic devices and even pacemakers. Hold the safety distance recommended by the manufacturer

• Avoid sparks: Magnets must not be installed in potentially explosive atmospheres as they can cause sparks.

To store magnets safely, you should observe the following measures:

• Keep a distance: Store magnets at a sufficient distance from each other or use non-magnetic spacers to prevent uncontrolled contraction.

• Store in a dry and cool place: Store magnets in a dry environment at room temperature to prevent corrosion and loss of performance.

• Keep away from electronic devices: Keep magnets away from electronic devices, data storage media and credit cards as strong magnetic fields can damage them.

• Keep out of the reach of children: Magnets are not toys and should be kept out of reach of children to prevent ingestion and injury.

• Use protective equipment: When handling very strong magnets, it is advisable to wear protective gloves and goggles to avoid crushing and splintering injuries.

• Place on a metal surface: Storing magnets on a metal plate is safe as they adhere firmly and are protected against uncontrolled collisions. Take care not to place the magnets too close together.
