Products/Shop Permanent Magnets NeoAlphaMagnets
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. |
