Disc magnet Ø 15.0 x 8.0 mm N45 COPPER - holds 7.2 kg
The copper-colored surface makes these strong neodymium magnets an eye-catcher on every magnetic strip or magnetic glass board. Go new ways on the pin board and fix your notes, pictures, etc. with these super magnets in copper.
In contrast to the nickel or epoxy coating, this copper coating is more easily rubbed off, so these magnets should only be used for decorative applications.
Identical magnetic discs with Ø 15 x 8 mm are also available with a nickel coating:

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.
