The bar magnet 2 of Figures 6 and '7 has lateralrecesses 23 for receiving screws, which recesses are moulded in the pressing operation. Handle Magnets. Figure 8 is a longitudinal section of a disc form pressed magnet with pressed on pole plates. Permanent magnets are made of iron alloys with high carbon content and greater or smaller additions of chromium, cobalt, copper and so forth.

The process consists in reducing a permanent magnetic alloy, such as an alloy of nickel, aluminum and steel having high coercivity and high remanence to powdered condition, followed by mixing the powder with a binding medium such as phenol formaldehyde resin, followed by molding or otherwise forming the mixture of the powder and the binding medium, followed by magnetizing the material.
A lot of magnets are shipped to our customers each day. All Rights Reserved. The upper die 3 is also surrounded by a magnetizing winding 6, which can be connected to a source of direct current independently of the winding 5. After cooling of the pressing it is removed from the mould and magnetised in the usual way in a strong magnetic field. These alloys are distinguished by high coercivity and remanence, but the high carbon content and the addition of the mentioned metals result in great hardness of these magnetic steels so that working of them, in particular machining, as well as shaping by forging or pressing involves considerable difiiculty and may only be possible in unhardened condition.

A similar procedure is adopted according to the invention if neither synthetic resin nor easily mouldable plastic nor pulverulent artificial materials are used as the binding medium, but a metal with a lower melting point than the magnetic alloy is used, the preliminary magnetisation being effected before the solidification of the fluid binding medium.

It will be seen that the invention consists essentially in providing the upper die of the press with a separate magnetizing coil; the die is first lowered on the molding powder in the unenergized state; when in the lowest position, the coil is energized and the die is raised, and finally also the conventional magnetizing coil of the mold is energized, and the molding powder is compacted by lowering the upper die again.
The process of the invention may be used for the manufacture of round or angular discs, or rings or magnetic bodies of other shapes. It has further been found that the coercive force of pressed magnets in this manner reaches a still higher value if according to the invention the mixture of ferromagnetic materials and binding medium is subjected to a magnetic field during the actual making or pressing operation.
NdFeB magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discs. According to the invention the whole process of production can be further simplified by the forming of the mixture by pressing or casting with heating of the mould as well as the insertion of the pole plates in the magnet body being effected in a single operation.

Sintered SmCo Magnet. In further development of the invention the procedure in making the pressed permanent magnet is such that the mixture of ferromagnetic material of high coercive force and binding 5 medium is first preliminarily pressed while under the action of a strong magnetic field, then the magnetic briquette is obtained finish pressed under high pressure and advantageously simultaneous heating, and thereupon final magnetisation effected maintaining the same field direction as in the preliminary magnetisation.

This choice of grains of various sizes results in better filling of the space occupied and close contact of the grains one with another, so that within the permanent magnet pressed from these grains, there is a far reaching magnetically con ductive connection among the individual ferromagnetic particles.
