NeoDeltaMagnet® (NdFeB)Permanent magnets made of Neodymium-Iron-Boron (NdFeB)Manufacture of customer-specific magnet dimensions.
NeoDeltaMagnet (NdFeB) is the "strongest" magnet material available. The following standard magnets are generally available from stock. General tolerances according to DIN 7168. Without a protective coating a rust-like surface corrosion occurs with NdFeB magnets under air humidity. Our standard magnets are supplied with a high-quality coating tin on nikkel.
|
|
NdFeB magnets are hard and brittle. To avoid breakage an impact or pressure load should be avoided. As with all magnet materials, the maximum operating temperature depends on the correct magnet dimensions (L/D-ratio in the operating point on the width x height line). |
|
If the magnet dimensions are incorrectly chosen with insufficient thickness in the direction of magnetisation, irreversible loss of magnetisation will occur already below 100 °C. All standard magnets are supplied magnetised.
All dimensions in mm. |

Small orders: Payments from foreign countries result in additional bank charges, therefore we charge an additional lump sum of 15,- Euro for all foreign orders with a goods value less than 153,- Euro.
Please ask for our Conditions of sale, delivery and payment in english and our export conditions for your country. |
|
|
Beside standard magnets usually available from stock, we also supply magnets made from different magnet materials, so that the magnets can be optimally adapted to the application in terms of both dimensions and material. |
|
Segment magnets for motors, magnets for couplings or for use at high temperatures should, for example, have a higher coercivity H, while magnets for holding applications or sensor activation should have a higher remanence B. |
|
|
A range of characteristics for available magnet materials are listed below for selection. The numbers in brackets are the code numbers according to DIN 17410 or IEC 404-8-1.
|
|
We will be delighted to help you select the suitable magnet material for your application. |

Manufacture
The magnets we produce are processed on modern processing machines with diamond tools. Complicated shapes such as segments are eroded.
Surface coating
NdFeB magnets can only be used at an air humidity up to 50 % without condensation if no special coating is used. For most applications a galvanic coating is necessary. We recommend the proven coating tin plating and for particularly high resistance in a damp climate tin plating on nickel . The thickness of the layer is about 15 µm. For more information please request our information sheet Surface Coating for Permanent Magnets Made from NdFeB . The NdFeB magnet materials Vacodym 655HR/633HR and 677HR mentioned above are materials with high corrosion resistance |

Tolerances
Manufacturing tolerances should be agreed on. Sintered materials (like NdFeB magnets) are hard and brittle, therefore small instances of mechanical surface damage such as cracks on the edges and hairline cracks are not always avoidable. For series productions the preparation of limit samples has proven effective.
Influence of temperature
The max. temperature at which a NdFeB magnet can be used depends on the dimension ratio of the thickness in the direction of magnetisation to the size of the poles (L/D-ratio, see also "Magnet design"). The max. operating temperature can be determined with BHtemperature curves by dimensioning the thickness of the magnet in the direction of magnetisation for fixed pole sizes. |
