  • The product conforms to the European RoHS Community legislation

    The product conforms to the European RoHS Community legislation The product conforms to the European RoHS Community legislation (2002/95/EG - RoHS - Restriction of Hazardous Substances) relating to the use and the employment of certain hazardous substances in electrical and electronic devices.

  • Safety Notice

    NdFeB magnets are hard and brittle. Especially with thinner dimensions / higher adhesive forces, these can easily break or splinter! An uncontrolled impact of two magnets as well as an external, mechanical shock or pressure load should therefore be avoided!
  • Determination of the magnetic force

    The adhesive force of our magnets is determined at room temperature on a polished plate made of steel S235JR (ST37) with a thickness of 10 mm by the vertical withdrawal of the magnet (1kg ~ 10 N). A different value down to -10% compared to the specified value is possible in exceptional cases. In general, the value is exceeded. Please note that for thinner, painted and not absolute plan undergrounds the adhesive force represents only one raction of the specified values.

Sehr Zufrieden

11 Feb 2021

Kleine Magnete ganz groß! Dienen zur variablen Befestigung von kleinen Kunstwerken auf einem (Eisen-)Metallregal. Jetzt "purzelt" nichts mehr durch die Gegend und die Magneten -im Inneren verbaut- sind nicht zu sehen! Beinahe Zauberei :-)

Entspricht unseren Vorstellungen.

Tolle Magnete mit sehr guter Haftkraft

15 Jul 2019

Alles wie erwartet. Einen Stern Abzug gibt's jedoch für die unnötige Verpackung. Nervig alle 10er Packs (ich hatte 360 Magneten bestellt) aufzufummeln - ganz zu schweigen vom damit einhergehenden Plastikmüll.

Für unsere Arbeit bestens geeignet.

Verwendung für Versuche. Das Produkt kann man bedenkenlos weiter empfehlen.
