What does it mean when I see something like " lot of 6061 aluminum tubes" ?
I mean what does the number mean and how can I make sense of it ?

Thanks !


The alloy. If it's 6061-T(something) then the end numbers specify the
heat treat.

Take a look at http://www.matweb.com for details on specific alloys
(dunno where you'd go for an overview, but searching on "aluminum
alloys" might help).
