a piece of 6061 alum tube (1/8 wall) 1" x1 " x 36 " weights 1.4 lbs
the weight difference between alum and steel is not very much when the steel is half the size
for teams who want an easy material to work with without having to buy all the attachment components with extrusion, think steel. much easier to weld, much less expensive, locally available everywhere, easy to machine
you might want to consider this when looking at materials for the upcoming season

I gotta agree with greg on this one... we have used NOT STEEL but aluminum tube... as long as its welded right... you are good to go... most of the years out bots has been a pushing bot... probably at the end of the season we will see one or two bends but nothing really bad. Extrusion are good too... we have used it during 2002 season and it worked great...
