Just out of curiosity does anyone know what gauge aluminum foil is?

[ChuckD]

atrain,
According to the Aluminum Association;
aluminum foil is considered "less than .006"
plate = 1/4" or more
sheet = .249" to .006"
foil = less than .006"
I just found this out last night, then I see this post today, so there you have it .

[atrain185]

thanks chuck

[Bobcatter]

Great information, thanks. I formatted it into Word so I could print and post it. Sheez, allergies, keep me up all night....

Okay, I made the file smaller, so I could upload it. You can put your own title on it.

[Arcie]

Thanks - for your efforts getting all the info to line up in "word". A real good refernce!

[Lanmanb4]

Does anyone know what the gauge of typical car body metal is ?
Uhmmm particuliarly the older vehicles like a TR-8 ??

[fun4now.]

newer cars can go to 26gage but most older are closer to 18.
thanks for the chart, verry helpfull.

[metalman]

Had to save that. Thanks for the chart!

[mla2ofus]

My thanks to Vipermanz and Bobcatter for the chart. I printed off 2,one for my shop and one to make bets on how thick 10 ga is. Everyone i've ever talked about it w/ has always said it is 1/8", including myself!!!!
Thanks again,
Mike

[codearc]

i allways thought 10 gauge was 3.2mm thats what the old guys refer to in old money welding rods 12 gauge was 2.5

I found this online at davesport.com

Grade and Description Chemistry Tensile Yield Rockwell Hardness
Units typical ksi ksi typical

ERW tube C .08-.13
Mn .30-.60

As you can see, DOM tubing is nearly twice as strong in tension, and more than twice as strong in resistance to bending in comparison to the ERW tube. Also, the 4130 chromoly tube is only 20% stronger than standard DOM in tension.

Thanks guys
Great infos

[BWS29128]

Can someone PLEASE explain to me why I didn't find this message board until last week, when I really needed all this info 3 weeks ago???



Hee Hee

[smokeshow]

Great info...

Saving most of it...

[fun4now.]

well at first glance one would think this is very helpful. BUT all it really dose if confuse you even more ???
none of the #'s match ???what chart do we trust ??

15 .0673


at first i just thought it was a simple question of rounding it up to keep the # from going on forever, but???? 20 gage .0375 and 20 gage .0359 are way to far to be rounding for simplicity sake ?? so what gives ?? must be a tolerance thing ??
the only solution i see is ....

[Magnetic Mechanic]

blow this up 2x to read it

[ddog]

very helpful!!!!! printed a copy for the tool box... Thanks everyone

[davidmn]

In the start window I get the button 'Try It' which I clicked. But it still ends after 10 minutes.

[cranest]

Just to point out ferrous metal sheet and aluminum sheet gauge numbers refer to different thicknesses, meaning 10 ga. steel sheet is different thickness that 10 ga aluminum sheet. Though there are several good sources on the web, I like Aircraft Spruce and Specialty's info sheets out of their online catalog. The catalog is worth having just for the info, just like the old Starrett catalogs, verituble encyclopedias of measuring and setup info. Try this page:

[wagin]

Great information, thanks. I formatted it into Word so I could print and post it. Sheez, allergies, keep me up all night....

Okay, I made the file smaller, so I could upload it. You can put your own title on it.

thinks guy for the printable info. I had written down the common guages used and posted it on my tool box for purchasing info. This is more better. Thanks again.

[Oldiron2]

Machinery's Handbook has these plus other 'odd' and British standards too. It is a very good reference book, although having the chart printed out for your wall or toolbox is also a great idea.
Well, after doing a search here, I see that the Handbook has been mentioned on site fairly regularly, so I won't say more now.

[Jonesy70]

The chart is going on my wall and I will be handing out copies to my students....It well be a lesson in the making...I always used my pipe fitting book to look up thicknesses...this chart puts all the info in one spot...THANKS

[welderShane]

Wow all this time and i didnt even notice this thread. I just printed one out. Thanks alot!!!
