Why, not at all! After he wrote, "Since you seem to know so much, why don't you tell me?" I think that I can ask a simple question a second time just in case he missed it the first time. (shrug) I have absolutely no ulterior motives here. I do some amateur welding, and if there is an aluminum alloy that is as malleable as steel, I really want to know!
But what I suspect is that Ford's "military grade aluminum" is akin to Ford Motorcraft Transfer Case Fluid, P/N 1076275-00. Ford never published what its transfer case fluid was - no specs, nothing. Unless you wanted to take the chance on sabotaging your expensive transfer case or void the factory warranty you paid for if you bought your truck new, you were pretty much obliged to use it. So I did - FOUR TIMES. And then my transfer case failed at 85,198 miles. And after I paid $1,719.82 to have the transfer case replaced at my local Ford dealership they informed me that the proper fluid to use is Mercon LV. Apparently Ford has discontinued its proprietary fluid, and Mercon LV is now the recommended fluid in all applications that previously called for the proprietary stuff. Do you think that it might be possible that Ford's secret proprietary transfer case fluid might have been inferior and contributed to the expensive failure I had? I do sure do, given that it was serviced so regularly with the proprietary factory fluid.
So I am wondering if Ford's magic aluminum is similar to its magic transfer case fluid in that we will never know what it is. If FordTechOne knows, I'd like to know, too, and I bet I'm not alone. It's as simple as that.
