Description
Zum Löten von Zink und Zinklegierungen geeignetes korrosionsfestes Lot. Profile, Pressteile, 'Walz- und Decolletage- material, Gussstücke aus Zinklegierungen konnten bisher nicht einwandfrei sauber und oxydfrei mit der Brennerflamme oder dem Lötkolben gelötet werden.
Gegenstand vorliegender Erfindung ist nun ein zum oxydfreien Löten von Zink und Zinklegierungen geeignetes korrosionsfestes Lot. Dieses korrosionsfeste Lot besteht aus einer Zink und Cadmium enthaltenden Le gierung.
Die Schmelztemperatur des Lotes kann durch das Mengenverhältnis zwischen Zink und Cadmium beeinflusst werden und kann somit dem Werkstoff weitgehend angepasst werden. Ausserdem kann durch einen Zusatz von F bis 3 % Antimon die Lötung noch ver bessert werden.
Nachstehend sind einige Ausführungsbei spiele des Erfindungsgegenstandes angege ben.
<I>Beispiel 1:</I> Lot, aus einer Legierung von 83% Cad mium und 17 % Zink (Eutektikum) bestehand. Fieses Lot. ist leichtflüssig, glatt bindend und besitzt eine Schmelztemperatur von zirka 266 . Beispiel <I>2:</I> Lot, das aus einer Legierung besteht, wel che Zink und Zink-Cadmium-Eutektikum enthält und eine Schmelztemperatur von z. 73. 283 aufweist. Dieses Lot ist strengflüssig und glatt bindend. <I>Beispiel 3:</I> Lot, welches aus einer Legierung besteht, die sich aus 37 % Zink,<B>61%</B> Cadmium und <B>)</B>% Antimon zusammensetzt. Dieses Lot ist feinkörnig, gibt eine saubere, glatte Bindung.
Corrosion-resistant solder suitable for soldering zinc and zinc alloys. Profiles, pressed parts, rolled and décolletage material, castings made of zinc alloys could not be soldered perfectly clean and oxide-free with the burner flame or the soldering iron.
The present invention now relates to a corrosion-resistant solder suitable for oxide-free soldering of zinc and zinc alloys. This corrosion-resistant solder consists of an alloy containing zinc and cadmium.
The melting temperature of the solder can be influenced by the quantitative ratio between zinc and cadmium and can thus be largely adapted to the material. In addition, the soldering can be improved by adding F to 3% antimony.
Below are some Ausführungsbei games of the subject invention are indicated.
<I> Example 1: </I> Solder, consisting of an alloy of 83% cadmium and 17% zinc (eutectic). Nasty plumb bob. is light-bodied, binds smoothly and has a melting temperature of around 266. Example <I> 2: </I> solder which consists of an alloy which contains zinc and zinc-cadmium eutectic and has a melting temperature of e.g. 73.283. This plumb bob is very fluid and binding. <I> Example 3: </I> Solder which consists of an alloy composed of 37% zinc, <B> 61% </B> cadmium and <B>) </B>% antimony. This solder is fine-grained, gives a clean, smooth bond.
