They sell 26 gauge steel at Lowe's, which according to one web page should be .0179 inches thick. The aluminum is .016 inches thick.
Anything much thicker would be too thick to fit.
I thought steel was stiffer, and one page says it is three times as stiff, http://22.214.171.124/search?q Êche:EUguRlm-7ugJ:www.bebop.com/old%2520web%2520text/pages/appliedmata101.html+aluminum+steel+stiffness&hl=en&lr=lang_en|lang_iw|lang_es but I found some page on bicycle frames that seemed to claim that aluminmum was, although I guess that is aluminum that is as thick as it must be to be as strong as steel. http://126.96.36.199/search?q Êche:7DA0YencvJYJ:www.epinions.com/content_1285660804+aluminum+steel+stiffness&hl=en&lr=lang_en|lang_iw|lang_es But another webpage says that current alloys of aluminum are as ?strong? as steel.
I had this small sheet of something, I guess it is aluminum**, and I made a bracket for a cup holder for my cup-holderless car.
**It conducts electricity, but isn't attracted to a magent. It's silver color and came out of a stereo amp or something. 6" x 8" I don't remember what it did there.
