This is for swing arm. Very similar to the one on a desk lamp.

You could contact some large aluminum manufacturer, they exist also
smaller
but are not always in the catalogs.

What is the application?

Round tubes I have found very small in applications for the medical
sector.
(But also rather expensive)

I am looking for source(online or otherwise) small(less than 1/2") steel
or
aluminum square tubing.
The smallest tubing most sources have is 1/2" which is too much for my
application.

BTW: I am in San Francisco Bay Area.
