aluminum wire for soldering?

[[email protected]]

recommend a retail source or recycled source of 1xxx aluminum that is
solderable with standard flux and solder?

a suggestion was bus bars-are bus bars solderable?

I don't know what you're calling standard flux and solder (though this
brings to mind the various tin/lead or modern lead free types of solders
suitable for yellow metals, tins and steel). There is aluminum solder
which can be used for aluminum and works quite well with some practice.
The process is closer to welding with what I've used and these soldering
rods are available at many welding suppliers, automotive and farm
mechanical supply places. Bus bars I've seen were usually Aluminum,
brass or plated brass. What sort of process do you anticipate - just
curious.

IME aluminum is solderable if one cleans the surface *immediately* prior
to applying solder...IOW, heat the metal, scrape the area to be soldered
while hot and feed in the solder. It's a PITA, but marginally doable.

reads like a strong joint is produced if 1xxx is used with the aluminum
rod .
where's the 1xxx?

the idea is to make eyeglass frames-question before is: does an
eyeglass frame member-given the thickness-survive heat necessary for
penetrating aluminum oxide with aluminum rod?

Exterior strut armatures are very popular for sculptors who like to
work out the figure and pose as they go.
Aluminum wire, hung from the armature makes it easy to bend arms and
legs and make modifications as you go... and for that style of working
they are fine.

Re: Your thoughts on Loveland Academy of Arts supplies-from henri>
you can buy rod for soldering the aluminum together at home depot.
Thats what I do. I solder the aluminum wire together. Then it bends
however I need. Bernzomatic Aluminum Solder Rod Model 4627170 Has
brinnell hardness of 100, Working temperature to 750 degrees F. Use to
join and repair aluminum obj...

There is such a thing as copper-clad aluminum. Perhaps that is what you are
referring to?

Also, some aluminum alloys can be successfully soldered with ordinary
materials. One way is to use a coating of light oil or rosin flux and then
scrape the oxide film off. The coating will prevent the aluminum from
immediately re-oxidizing. I have used 3-in-1 oil, by the way.

Aluminum is highly reactive with oxygen and that is what makes it so
difficult to solder. As soon as you remove the oxide film, it immediately
reforms. That's where the oil or flux coating comes in.

i tried covering aluminum with flux, then filing surface, soldering
with transistor solder and 25 watts-the aluminum was cut thin from
Home Depot stock-no flow, no bond.
web search revealed type 1xxx aluminum is used for soldering that
should be the "also"
G's suggestion to search for aluminum solder, which should be obvious,
thanks G leads to the sculpture people through the rod: stiff wire may
be workable.
!xxx? I'll look for bus bars.
IME Aluminum is a web clearing area for al scrap to china. go see.
