Sheet Metal Strength?
Sheet Metal Strength?
(OP)
Hello
I need to determine the 3003 H-14 aluminum equivalent of 304 stainless steel. For instance, I have a .125" thick 304 S/S sheet metal part. I need to determine the thickness of the aluminum sheet metal that will have the same strength as the existing stainless steel part. It's been a while since I've done this and I'm lost. Can anybody please help me get started? Thanks!

Need to have some idea of the application, geometry, loading, etc.

Can you post a picture of the bracket installed in its intended use. Is this bracket mounted in an enclosure or a vehicle (plane, or truck)

3003-H14 aluminium has a yield strength of 145 MPa.
If your Al part needs to have equivalent strength to 3 mm thick 304 stainless steel, then the thickness would need to be t =(200 MPa/145 MPa)· 3 mm = 4 mm.

Cory, I double checked my calcs according to your suggestion and it seems I was doing it correctly. Thanks again.

Think about a rubberband and a string. If you incrementally add weights hanging from a string and rubberband and they both break at the same weight, does that mean they were the same strength? Not if your concern was you wanted a small deflection from the rubberband, similar to the string. Then you'd need alot thicker rubberband...
