|Techniques for Soldering Aluminum Alloys|
|Keywords: Aluminum, Soldering, Flux|
|Aluminum alloys, being a light weight, very abundant, relatively strong, and a low cost metal, has seen wide application use in many different fields. Many applications would like to join this metal to aluminum or other metals with a low temperature joining solution like soldering to preserve the aluminum alloy’s physical characteristics, provide a useful thermal or electrical pathway, and eliminate costly aluminum plating options often seen today. In response, techniques have been developed to directly solder aluminum with multiple methods such as flux, flux paste, coated solder preforms, flux cored solder wire, solderpaste, and pre-tinning the aluminum surface.|
