English material specs needed.
Hi,
I have several projects coming up and I'm looking for English aluminum material specs. Im looking for aircraft and general use English aluminum information, including strengths of material. I need the info for my component documentation and proper American material substitution. Thanks Bill

I think the easiest way to start is, what were the top five common aluminum alloys used during WW2? B

I have done a little bit of aircraft work, all I know is that the material that the aircraft people supplied me with, was 3/4 hard and it was annealed in some sort of salt baths, then we wheeled, and when hard again, it was annealed again, then wheeled again till the desired shape was achieved. No flame or heat of any kind was allowed! What a job that was

Bill: I did some cruising through the Spitfire drawings I have access to. The Brits did stuff weird on their drawings. The few that I could find material specs on, show just a D.T.D. number, and one BOM listed the materials as Dural and Alclad, with spec numbers. I did run across a pointer on another board, to a file with the D.T.D. numbers and the spec descriptions.
Here's a link, and it should be of some help. https://www.scribd.com/doc/197257502/Dtd-List

"Obsolete" is a common term in this list. "Aluminum-silicon sheet" is one that was a no-go decades ago. I surmise that eliminating the obsoletes will make the remaining choices easier to obtain and use, and it never hurts to use a higher-grade alloy where applicable. Kermit may have a crossover material list over at Fantasy, in FL. Paul might be able to help you.

Unstressed items like engine cowlings and fairings were often made of 1XXX that you can push around with your fingers. If you can give me a DTD (Directorate of Technical Development) or BS (British Standards) spec' I'll tell you what it is in modern language. Will

Hi Bill, I'd recommend borrowing/renting an alloy gun for the day you have all your PiQ (parts in question) laid out to solve the alloy ID mysteries therein: http://electricaltechno.com/products...er-PMI-Gun-NDT or perhaps NiB: http://www.tzsupplies.com/olympus-in...6500-i4979029/ (Prices are down a LOT from 10 years ago ) (Love seeing the old XP82 flying now) XP82.jpg
