NeoAlphaMagnet® (NdFeB, plastic bonded)

Permanent magnets made of Neodymium-Iron-Boron (NdFeB), plastic bonded

NeoAlphaMagnet is not sintered like other magnets the magnetic powder mixed with epoxy resin is hot pressed in form tools. Normal tolerances are therefore within ± 0.1 mm.

Unmagnetised standard magnets can be machined and thus modified according to customer specifications.

Product Description

For larger quantities, magnets made from NeoAlphaMagnet can be produced in customer-specific pressing tools with small tolerances and smooth surfaces. We will be glad to assist you in the development of forms suitable for tools. The magnets are isotropic, i.e. they have no orientation and can be magnetised in any direction. Multiple pole magnetisation is also possible with special magnetising equipment. In normal environmental conditions (e.g. room temperature and relative humidity < 50%, no condensation), these magnets can be used without special coating. Under more corrosive conditions we suggest plastic coating.

We supply all standard magnets magnetised in the given magnetisation direction.

We supply the following standard magnets at short notice, generally from stock.

All dimensions in mm.

General tolerances after DIN 7168.

More magnetic properties

For custom made orders in large series we can offer and supply NeoAlpha- Magnet in various material qualities. Material data is given below. Consequently, the optimum magnetic material can be chosen for the required use. The forming of reliefs and holes can be provided in the direction of magnetisation in the pressing tools.Transfer moulds are complicated to make and are therefore more costly than pressing tools.

Owing to its isotropy, NeoAlphaMagnet can be magnetised in any direction. NeoAlphaMagnet is also very suitable for rings with narrow, multi-pole magnetisation on the circumference.

Example of a ring magnet with multiple magnetisation (can be produced in special magnetising unit).
