Sheet Metal Gauge Tables
Sheet Metal Gauge Tables
(OP)
I just tried out the sheet metal gauge tables in SolidWorks. According to the tables, aluminium, 12 gauge, has a thickness of 2.5mm. According to every other reference I can find, 12 gauge aluminium is .0808" (2.06mm) thick.
I am located in Canada. Is this gauge valid somewhere else?
It looks I should not use these tables.

Excellent catch. In comparing SM gages in SW with the info at ht
it looks like all the aluminum gages are off, but the steel ones are good.

The moral of this story is that you specify the thickness of your sheet metal parts in inches or millimeters. Never, never, never call up sheet gauge.

Thanks.

Moral of the story, design to reality, not theory. Or, when theory and reality don't match choose reality.
We have not yet modified or created a custom gage table (How easy is this to do?). We want to do that just to make thickness selection a simple click and pick up the material properties at the same time. For now we are selecting the xx gage galvanized and then changing the thickness to represent the reality of the situation. Our life is MUCH better now.
BTW, drawoh is correct that material thickness is supposed to always be specified by its thickness, not its gage. It is acceptable to also reference the gage, but the thickness must be stated explicitly. This is even stated in the published gage tables from the material suppliers (at least the ones on my shelf).
