" Alliage ".
La présente invention a pour objet un alliage pour in- struments acoustiques, par exemple pour les cloches, lequel en dehors du cuivre et de l'étain avec les impuretés normales, contient jusqu'à 50% de zinc et présente une texture consis- tant en cristaux composites Ó et eutectoïde. L'alliage peut aussi contenir des additions d'aluminium, fer, manganèse, nickel, plomb, antimoine et silicium.
L'alliage présente, en tant qu'il est compris dans la partie hachurée du .'diagramme
<Desc/Clms Page number 2>
ternaire (voir le diagramme) même quand il renferme de petites proportions d'étain et de fortes proportions de zinc, une structure semblable à celle des alliages de cuivre-étain ayant une teneur de 13,9 à 26,8% d tétain. Quand on ajoute d'autres métaux, excepté le cuivra, l'étain et la zinc, les lignes de démarcation de la partie hachurée du diagramme ternaire peu- vent être replacées et, en outre, des éléments séparés peu- vent se former dans la structure de l'alliage.
Il a été reconnu que l'alliage qui fait l'objet de la présente invention peut être obtenu à un prix extraordinaire- ment bas,tout en possédant pratiquement lesmêmes qualités que les bronzes de cloches de cuivre-étain à 16-24 % d'étain, avec cuivre et impuretés pour le reste. En particulier le bronze de cloches qui vient d'être mentionné et le nouvel al- liage présentent une concordance très marquée quant aux pro- priétés suivantes : coefficients de résistance, dureté, qua- lités acoustiques, couleur, aspect de la cassure, point de fusion, intervalle de solidification, fusibilité, retrait et facilité du traitement.
Les qualités acoustiques du nouvel alliage sont même un peu supérieures à celles des bronzes à l'étain et sa fusibi- lité est parfaite, de sorte que l'on peut couler sans diffi- des pièces irréprochables, portant toutes sortes d'ornements, propres et nettes, sans risque de soufflures. Pour obtenir les qualités mentionnées ci-dessus correspondant à celles des bronzes d'étain, il faut tenir le total des pourcentages zinc étain + dans les limites de 16 à 26. En adoptant la composition appropriée et en évitant de surchauffer, on pré- vient presque complètement la formation de vapeurs d'oxyde de zinc à la fusion et à la coulée.
Il n'est pas nécessaire, en règle générale, de désoxyder; cependant on peut, sans in- convénient, procéder à la de/oxydation par les procédés connus.
Un alliage approprié est par exemple le suivant :

Cuivre ..eew .ow oew eeeleeeooow eoew ee..o59,30 o Etain....................................... 6 Zinc........................................ 34 Nickel...................................... 0,50 Silicium.................................... 0,20
Dans certains cas, il y a avantage à soumettre l'alliage à un traitement thermique. Par traitement thermique on entend un échauffement au rouge, un refroidissement brusque ou un refroidessement brusque avec recuit subséquent.

"Alloy".
The present invention relates to an alloy for acoustic instruments, for example for bells, which apart from copper and tin with normal impurities, contains up to 50% zinc and has a consistent texture. in Ó and eutectoid composite crystals. The alloy may also contain additions of aluminum, iron, manganese, nickel, lead, antimony and silicon.
The alloy present, as it is included in the hatched part of the diagram
<Desc / Clms Page number 2>
ternary (see diagram) even when it contains small proportions of tin and high proportions of zinc, a structure similar to that of copper-tin alloys with a content of 13.9 to 26.8% tin. When other metals are added, except copper, tin and zinc, the lines of demarcation of the hatched part of the ternary diagram can be replaced and, in addition, separate elements can form in the alloy structure.
It has been recognized that the alloy which is the object of the present invention can be obtained at an extraordinarily low cost, while having substantially the same qualities as the 16-24% copper-tin bell bronzes. tin, with copper and impurities for the rest. In particular the bronze of the bells which has just been mentioned and the new alloy show a very marked agreement as to the following properties: resistance coefficients, hardness, acoustic qualities, color, appearance of the fracture, point of melting, solidification interval, fusibility, shrinkage and ease of processing.
The acoustic qualities of the new alloy are even a little superior to those of pewter bronzes and its fusibility is perfect, so that one can cast without difficulty irreproachable pieces, bearing all kinds of ornaments, clean. and clean, without risk of blowholes. To obtain the qualities mentioned above corresponding to those of tin bronzes, the total of the percentages zinc tin + must be kept within the limits of 16 to 26. By adopting the appropriate composition and avoiding overheating, we prevent almost completely the formation of zinc oxide vapors on melting and casting.
As a rule, it is not necessary to deoxidize; however, the de / oxidation can be carried out without inconvenience by known methods.
A suitable alloy is for example the following:

Copper ..eew .ow oew eeeleeeooow eoew ee..o59.30 o Tin ................................. ...... 6 Zinc ........................................ 34 Nickel ...................................... 0.50 Silicon ........ ............................ 0.20
In some cases, it is advantageous to subject the alloy to a heat treatment. By heat treatment is meant red heating, sudden cooling or sudden cooling with subsequent annealing.
