    Aluminum extrusion

    Can somebody comment on the strength and stiffness of aluminum extrusion.
    In particular perhaps something like this?


    Thats 1" by 1", and 1002 alloy

    yup, 1000 series al. is of the pure al sort........
    what are you going to use it for?
    the inside construction is for stiffening purposes......
    hmmm..you sure that's 1000 series?

    Doesn't "look" very strong.

    Looks like the stuff used as supports in cheap carports.

    Pretty close. It's used to mount moveable wall (cubicle) systems in offices. The wall panels have an edge that slide into the channels on the two sides. BTW they also come with channels on three sides for "T"s and on opposite sides for straight walls. I've used tons of the stuff. Back to the OPs question. No they are not strong at all. The wall panels are stiff by themselves so the connector extrusions don't have to be.

    I've no way of telling for sure if it is the 100 series. Im just trusting the specs the retailer gives me....

    Its going to be used as the structual frame of a medium sized CNC router with a 1HP spindle. Travels are:
    44" X
    24" Y
    4" Z

    Oh oh my scrap yard came through, it looks like i wont need that extrusion after all.

    HOWEVER, i iwll be using this:
    http://i19.ebayimg.com/02/i/05/49/cf/34_1_b.JPG

    1" x 3" 1030 alloy

    Im hoping this will be very stiff, and it seems reasonably lightweight.

    THey are modeartely strong. They don't take well to rotational forces though.

    That design is pretty much the industrial version of an erector set. We build cables racks, carts, and other misc stuff at work out of larger versions of those.

    I think i will go for that 1x3 then. Its cheap enough, it wont kill me to screw up. I saw some extrusion similar at the MIT museum hte other day, and it looks fairly strong. BUt this is even larger.
    It will be supporting a rail which a cutter moves on. THere will be two supports, basically i am making one of these:

    Except the supports for hte moving slide, rather than being a cut piece of aluminum plate, will be that 1x3 extrusion.
