Description

Verwendung von Bleilegierungen für Lote Als Bleche u. dgl. kennt man bereits Blei-Antimon-Legierungen, deren Sb-Gehalt io% nicht übersteigt, und es sind auch solche Legierungen mit einem Sb-Gehalt von q. bis 13°/o bekanntgeworden, die zur. Erzielung einer hohen Korrosionsfestigkeit, Härte und .Bruchsicherheit kleine Aluminiumzusätze erhalten und dann thermisch vergütet werden.Use of lead alloys for solders As sheets and the like are known already lead-antimony alloys, the Sb content of which does not exceed 10%, and there are also those alloys with an Sb content of q. until 13 ° / o became known, the to the. Achieving a high level of corrosion resistance, hardness and small break resistance Aluminum additives are obtained and then thermally tempered.

Es wurde nun gefunden, daß bei Blei-Antimon-Legierungen mit 8 bis i 5'/o Sb, also Legierungen eutektischen Gefüges, ein Zusatz von 111, Aluminium oder Magnesium oder einer Mischung beider Metalle ein Gittersystem erzeugt und die Festigkeit der Legierung erheblich erhöht.It has now been found that in lead-antimony alloys with 8 to i 5% Sb, i.e. alloys of a eutectic structure, an addition of 111, aluminum or magnesium or a mixture of both metals creates a grid system and the Strength of the alloy significantly increased.

Nach dem Vorschlage der Erfindung werden diese Legierungen zur Herstellung von Lot verwendet. Die Al-, Mg- oder AI-Mg-Zusätze verdreifachen die Festigkeit im Vergleich zu den zusatzlosen Pb-Sb-Legierungen, und man erhält ein Eutektikum, dessen Schmelzpunkt im wesentlichen jenem des reinen Zinns gleicht.According to the proposal of the invention, these alloys are used for production used by solder. The Al, Mg or Al-Mg additives triple the strength compared to the additive-free Pb-Sb alloys, and a eutectic is obtained, whose melting point is essentially the same as that of pure tin.

Hergestellt wird die Legierung auf eine an sich bekannte Weise, indem man im selben Tiegel Antimon und ein Salz oder Salzgemisch, z. B. Kochsalz, Kaliumchlorid, Lithiumchlorid, einsetzt, so daß ein Schutzüberzug erhalten wird, der die unmittelbare Berührung der Schmelze mit der Luft verhindert. Nach dem Zusatz des Kor rektionsmetalles wird die Masse vollkommen geschmolzen, dann langsam durch den Bleizusatz abgekühlt und somit die Legierung erhalten.The alloy is produced in a manner known per se by one in the same crucible antimony and a salt or salt mixture, z. B. table salt, potassium chloride, Lithium chloride, is used, so that a protective coating is obtained, which is the immediate Prevents the melt from coming into contact with the air. After the addition of the Kor rektionsmetalles if the mass is completely melted, then slowly cooled by the addition of lead and thus preserve the alloy.

Vergleichende Lötproben, die mit dieser Legierung und der handelsüblichen, 400/'o Sn enthaltenden Blei-Zinn-Legierung ausgeführt wurden, haben praktisch die gleiche Axialzugfestigkeit ergeben. Das Lot besitzt ein bedeutendes Fluß- und Haftvermögen sowohl auf Eisen als auch auf Messing, Kupfer, Zink usw., und es eignet sich daher besonders zur Herstellupg.v@on_ Schutzüberzügen.Comparative solder samples made with this alloy and the commercially available, 400 / 'o Sn-containing lead-tin alloy have practically the result in the same axial tensile strength. The solder has significant flow and adhesive properties as well as on iron as well as on brass, copper, zinc, etc., and it is therefore particularly suitable for manufacturing protective coatings.

Aufer diesen Vorteilen bietet die Legierung auch den erheblichen Vorteil, daß zinnarme Länder von der Einfuhr dieses Metalls unabhängig gemacht werden. Aluminium oder Magnesium oder einer Mischung beider Metalle, Rest Blei, zur Herstellung von Lot.In addition to these advantages, the alloy also offers the considerable advantage that tin-poor countries are made independent of the importation of this metal. aluminum or magnesium or a mixture of both metals, the remainder being lead, for the production of Lot.
