Abstract: A method for soldering aluminum or aluminum alloys is disclosed, together with an alloy useful in the method. The method includes heating, for example by using a torch, at least one aluminum piece to a temperature within the range of 90-150 degrees celsius, cleaning at least one heated surface thereof, for example by wire brushing, further heating the cleaned piece to a temperature within the range of 350-490 degrees celsius, and applying, for example by rub soldering, to the cleaned and further-heated piece a quantity sufficient to enable subsequent soldering, as required, of a tin/lead/zinc alloy consisting essentially of, by weight, from 1.7 to 2.2 percent aluminum, from 0.01 to 0.02 percent magnesium, from 45.9 to 50.4 percent zinc, from 14.2 to 34 percent tin, and from 16.6 to 36.7 percent lead.
