I am wondering if anyone would be so kind as to help me with a project. I am wondering what size aluminum square tubing it would take to build a "T" with the horizontal top being 4 feet in length and being able to hold 250 lbs. at each end and 1 ft. in from each end, totalling 1,000 lbs. I know what size tubing I need in steel but I would like to make the structure lighter and am not familiar with the strength of aluminum for such a cantilever. Just trying to see if aluminum is a viable option. Thanks, Bruce

Pure aluminium is too soft for construction purposes.
Many common alloys (ie silumin) has better strength/weight ratio, than ordinary steel.
But are more expensive.
Should also pay attention for the operating temperature and corrosion factors.

It might, but you've left out too much information.
