Description
Aimant permanent et procédé de fabrication de cet aimant. Le brevet principal a pour objet un ai mant permanent, caractérisé en -ce qu'il est formé au moins en partie d'un alliage -con- tenant du fer, comme composante principale, de 7 à 4() % de nickel et de 3 à 20 % d'alu minium. Ce brevet comprend également un procédé de fabrication de cet aimant, carac- térisé en ce que l'on fait ce dernier, au moins en partie, en un alliage de la composition in diquée ci-dessus.
On a indiqué dans ce brevet principal que l'alliage dont est fait l'aimant peut contenir du tungstène en quantité -comprise entre 0,5 et 8 %, .ce métal augmentant les qualités du- dit alliage.
Or, on a trouvé qu'une teneur en tungstène, dans l'alliage spécifié, inférieure à <B>0,5%</B> est aussi susceptible d'augmenter les propriétés magnétiques de l'alliage.
La présente invention comprend donc un aimant permanent et un procédé de fabrication de cet aimant. L'aimant permanent selon l'invention est formé, comme celui du brevet principal, au moins en partie d'un alliage .contenant ,du fer, comme composante principale, de 7 à 40 % .de nickel et de 3 à 20 % d'aluminium, mais il est caractérisé en -ce que ledit alliage contient en outre -du tungstène en quantité inférieure .à 0,5%.
La teneur en carbone de l'alliage formant l'aimant selon l'invention peut s'élever jus qu'à 1,5 %.
Cet alliage peut en outre contenir du chrome, dans certains cas à raison de 1 à 5 % , dans d'autres cas en quantité inférieure à 1 % . Il peut renfermer les impuretés habituelles en faible quantité. Il pourra -également contenir de petites quantités d'un ou de plusieurs des métaux suivants: cobalt, manganèse, molyb- -dène, vanadium, cuivre, qui améliorent ses propriétés.
Le tableau suivant: .donne la composition et les propriétés magnétiques d'un aimant se lon l'invention ainsi que, sous chiffre 1, -d'un aimant au tungstène tel que défini dans le brevet principal pour permettre une compa raison.

Permanent magnet and method of manufacturing this magnet. The main patent relates to a permanent magnet, characterized in -that it is formed at least in part of an alloy -containing iron, as the main component, from 7 to 4 ()% nickel and 3 to 20% aluminum minimum. This patent also includes a method of manufacturing this magnet, characterized in that the latter is made, at least in part, from an alloy of the composition indicated above.
It was indicated in this main patent that the alloy of which the magnet is made may contain tungsten in an amount -including between 0.5 and 8%, this metal increasing the qualities of said alloy.
However, it has been found that a tungsten content in the specified alloy of less than <B> 0.5% </B> is also capable of increasing the magnetic properties of the alloy.
The present invention therefore comprises a permanent magnet and a method of manufacturing this magnet. The permanent magnet according to the invention is formed, like that of the main patent, at least in part of an alloy containing, iron, as the main component, from 7 to 40% of nickel and from 3 to 20% of aluminum, but it is characterized in -that said alloy further contains -du tungsten in an amount less than 0.5%.
The carbon content of the alloy forming the magnet according to the invention can be up to 1.5%.
This alloy may also contain chromium, in some cases in an amount of 1 to 5%, in other cases in an amount of less than 1%. It may contain the usual impurities in small quantities. It may also contain small amounts of one or more of the following metals: cobalt, manganese, molyb- -dene, vanadium, copper, which improve its properties.
The following table: .gives the composition and the magnetic properties of a magnet according to the invention as well as, under number 1, of a tungsten magnet as defined in the main patent to allow a comparison.
