Perhaps you absolutely don't.
My statement is not broad or misleading. I find it silly when people are wrong about something they have probably never studied, and stating that what I said is "Not even close." is just ridiculous. You probably have no idea what a 6061 is, what properties it has, the applications that benefit from its use. Furthermore, you probably have no idea what a T6 does to most alloys. Or even what it is. You can read about precipitated alloys in any technical book.
Tempering efficiently improves an alloy's toughness, while reducing its hardness.
How does this pertain to the subject? The iPhones body, made from 6061? In this context(how the use of T6 Aluminum would have help lessen the issues that are arising with the phone bending) your statement is misleading.
Yes, I a sure you find it silly. Many people project onto others what they themselves lack, it's quite common.
