Raw magnets of hard ferrite

Block magnet of hard ferrite

PRODUCT INFORMATION:
For the production of HF magnets, tools are often required. Therefore, not every desired dimension can be realised. Simple forms and small quantities can be cut from blocks or bars. The surface is blank but not free of dust. The specified temperature refers to the maximum operating temperature of the material. The resistance may be reduced due to the geometry.

As an alternative to the standard we also offer individual solutions:
» customised dimensions
» modified directions of magnetisation
» other types of magnetisation
» further qualities

Magnetized via the height (H). When multipole magnetized the holding force is reinforced on the lacquered holding surface. On the surface not lacquered, however, the holding force is reduced.
* 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.
