I have a project where I want to replace some plywood with some aluminum plate. I want to retain roughly the same strength, but it is not life & limb critical.
The plywood to be replaced is actually 5/8" thick OSB (oriented strand board, a.k.a. "waferboard"). I want to use 6061-T6 aluminum plate to replace it, and I am wondering what thickness of aluminum plate would give me roughly the same strength as the original 5/8" OSB. My initial guess was to try half the thickness, which would be 5/16" 6061-T6 plate, but honestly I have no idea. I'd rather not waste unnecessary money if 3/16" or 1/4" would do the trick. I'm guessing 1/8" would be noticeably weaker than the 5/8" OSB.
Does anyone have some advice, or an online resource that gives approximate equivalences of strength between OSB and aluminum?
Thanks in advance for any help you can offer.
