Your statement got me looking at my design manual. So let's do a comparison.
Tensile ultimate strength 304 CRES 1/4 hard = 125 ksi. 7150-T6511 extrusion = 88 ksi. Steel wins.
Now the important stuff, the yield strengths were the material starts bending and for the stuff we are talking about, the point where it will stretch and let go of the rack.
Tensile Yield - 304 1/4 hard = 75 ksi. 7150-T6511 = 78 ksi. The Aluminum wins but it's close.
Tensile Ultimate - 304 1/4 hard = 51 ksi. 7150-T6511 = 80 ksi. The Aluminum wins this one hands down.
There many types of steel and aluminum and the aircraft grade aluminum alloys beat many types of steel in strength, especially in yield strengths. So your statement "There is also no aluminum that is stronger then steel, none." is suspect at best.
