Do you need flux to solder aluminum?

Aluminum and aluminum base alloys can be soldered by techniques which are similar to those used for other metals. Abrasion and reaction soldering are more commonly used with aluminum than with other metals. However,

aluminum requires special fluxes

. Rosin fluxes are not satisfactory.

What kind of solder works on aluminum?

Also the opposite to gold soldering, aluminum soldering works best with a high Tin content alloy, such as Indalloy 121 (Ind121; 96.5Sn 3.5Ag, 221°C eutectic) or any of the “SAC alloys” (Tin-Silver-Copper or SnAgCu) like Ind256 (96.5Sn 3.0Ag 0.5Cu, 220°C liquidus).

Can soldering iron melt aluminum?

Aluminum oxide cannot be soldered, so must be scraped off. Soldering must then be done very quickly, before more aluminum oxide forms.

Aluminum also has a relatively low melting point of around 660 degrees

, meaning you’ll likely need a special soldering iron with a lower temperature.

How do you make solder stick to aluminum?

Once you have bare aluminum, you

prepare a solution from the copper sulfate and just a little bit of ferric chloride

. Using salt with that solution apparently removes oxidation from the aluminum. Then using the same solution without the salt puts a copper coating on the metal that you can use for soldering.
