Description
Zinn im Überschuß und Zusätze von Cadmium und Silber enthaltende Lote für Aluminium sind bekannt. Bei derartigen Loten waren die Bestandteile des Cadmiums und Silbers so gewählt, daß der Schmelzpunkt des Lotes für das Löten von Blechen zu hoch war. Zudem fehlte diesen bekannten Loten ein Aluminiumzusatz, der die Festigkeit der Lötverbindung erhöht.Tin in excess and additions of cadmium and silver for aluminum are known. In such solders, the components of the cadmium and silver were chosen so that the melting point of the solder was too high for soldering sheet metal. In addition, these well-known plumb bobs were missing an aluminum additive that increases the strength of the soldered joint.
Diese Nachteile werden durch das im folgenden beschriebene Lot vermieden. -These disadvantages are avoided by the solder described below. -
Das neue Lot ist ganz besonders zum Löten von dünnen Aluminiumblechen geeignet, wie sie z. B. für Haushaltungsgegenstände und für Verzierungen an Häusern, für Dachrinnen u. dgl. verwendet werden, ist aber auch zum Löten von dickeren Aluminiumteilen vorteilhaft.The new solder is particularly suitable for soldering thin aluminum sheets, how they z. B. for household items and for decorations on houses, for gutters and the like. Used, but is also advantageous for soldering thick aluminum parts.
Das neue Lot weist einen sehr niedrigen Schmelzpunkt auf, der zwischen 180 und 200° C Hegt. Dadurch ist die Gefahr einer Verbrennung des Bleches ausgeschlossen. Das Lot weist ferner eine große Leichtflüssigkeit auf, die auf der Zugabe von Cadmium und Silber beruht. Das Cadmium ergibt ferner den Vorteil einer erhöhten Haftung des Lotes an dem. zu lötenden Gegenstand und einer hinreichenden Härte der gelöteten Stelle. Zudem ergibt sich der Vorteil, daß die gelötete Stelle vollkommen glatt ist, ohne daß eine nachträgliche Säuberungsarbeit notwendig wäre. Die Lötstelle braucht also nicht mehr geglättet zu werden. Gegenüber Loten, die Zink enthalten, ergibt sich· der Vorteil, daß das Lot nicht abblättert und in der Farbe der des Aluminiums gleicht, während die Zink, enthaltenden Lote sich schnell verfärben und weniger korrosionsbeständige Verbindungen ergeben.The new solder has a very low melting point, between 180 and 200 ° C. This eliminates the risk of burning the sheet. The solder also has a large light fluidity on the addition of cadmium and silver based. The cadmium also gives the advantage of increased adhesion of the solder to the. object to be soldered and a sufficient hardness of the soldered point. There is also the advantage that the soldered point is completely smooth without any subsequent cleaning work being necessary. The solder joint needs so no longer to be smoothed. Compared to solders containing zinc, the following results the advantage that the solder does not peel off and has the same color as the aluminum, while solders containing zinc discolor quickly and are less resistant to corrosion Connections result.
Die zu lötenden Aluminiumbleche mußten bisher vor dem Löten mit einem Flußmittel, z. B. Stearin, Kolophonium oder ähnlichen Stoffen, bestrichen werden, um die Lote leicht flüssiger zu machen. Dies ist bei dem neuen Lot nicht erforderlich.The aluminum sheets to be soldered previously had to be soldered with a flux, z. B. stearin, rosin or similar substances, can be coated to make the solders light to make it more fluid. This is not necessary with the new solder.
Das neue Lot besteht dem Gewichte nach aus 6o°/q Zinn, 25°/,, Cadmium, 7,5 °/0 Silber und 7,5 °/0 Aluminium.The new solder consists of the weights by from 6o ° / q tin, 25 ° / ,, cadmium, 7.5 ° / 0 Silver and 7.5 ° / 0 aluminum.
