PRODUCT NOTE:
NdFeB magnets can be produced in almost any desired dimensions and without tooling costs. Small quantities are therefore also possible. They are nickel-copper-nickel (NiCuNi) coated to protect against corrosion. The specified temperature refers to the maximum operating temperature of the material. Due to the geometry, the
resistance may be reduced.

As an alternative to the standard, we also offer customised solutions:
" customer-specific dimensions
" modified magnetisation direction
" other types of magnetisation
" other qualities up to N54
" increased operating temperature up to 220°C
" self-adhesive on one side with additional foil
" customer-specific shapes (e.g. cubes, cones, etc.).e.g. cube, cone, sphere, segments)
" other coatings (e.g. galvanised, gold-plated, epoxy-coated)

* The forces have been determined at room temperature on a polished plate made of steel (S235JR according to DIN 10 025) with a thickness of 10 mm (1kg~10N). A deviation of up to -10% from the specified value is possible in exceptional cases. In general, the value is exceeded. The type of application (installation situation, temperatures, counter anchors, etc.) sometimes influence the forces enormously. The values given are for orientation purposes.
