aluminum properties
anyone know where i can find structural properties of aluminum?  also, what is the most common aluminum alloy used for structural shapes?  what shapes are readily available?  and are there any special design considerations (asd, lrfd)?  thanks
check out our whitepaper library.
contructor provided information for project i was working on: alloy for plate/sheet - alclad 6061, class - t6, maximum allowable stress (for temprature from -20 to 200 deg. f) equal to 9.5 ksi. minimum yield strength = 32 ksi.
there is a aluminum design manual that my company recently purchased that i recomend highly....there are many design examples.  if you are not familier with aluminum design you really need this...i think it was like 40 bucks.  the web site is
look here for properties of just about everything:
most common aluminum alloys for structural shapes are 6061-t6 and 6063-t6.  i typically use asd.
be sure to note that allowable stress within 1 inch of a weld are significantly reduced because of the change in temper associated with the weld heat affected zone.
matweb.com - good place...  i checked the aluminum.org and the design manual was $175 for non  
i don't know if it's still available, but alcan publishes(ed) a small manual titled "strength of aluminum", including some information on limits states design.  it also has design information on aluminum extrusions produced by alcan.
backing up par060, the aluminum design manual he spoke of has everything you would need for aluminum design, including a design guide, commentaries, specifications, material properties and design examples.
i highly recommend getting this if you think you'll be doing any aluminum design in the future - the $175 is well worth it (especially since i didn't have to pay for it out of my own pocket!).
pylko...check the aluminum association for producers of shapes (
"aluminum structures - a guide to their specifications & design" by kissell & ferry, published by john wiley is an excellent textbook.
i highly recommend it if you want a decent understanding of the differences between steel and aluminum design.
