Maybe if this thread catches on, we can have similar threads about other materials used in bicycle frames.
The goal here is to dispel some of the myths and misunderstandings about a given material; in this case we'll discuss aluminum. As you all know, I'm early in my fabrication experience with aluminum, so I'm hoping that others here with more experience will jump in too. But I've been studying the material for a long time, and some of the most in-depth and interesting reading I've done has been in welding and heat treating texts. So I am happy to help with some of the science and metallurgy. Take notes. There might be a test at Ballers next spring.
I have my own topics I'd like to cover. But please, post questions and be interactive.
