How critical is it that I find out the type of alloy (6000, 7000 series, etc) for a decent weld job? I've tried contacting KHS but never got a response, and haven't had any success searching the internet either.
All I have to go on is the "Lite Concept - Aluminum Alloy" sticker pictured above. I know most KHS frames from this era were made with True Temper, did TT ever do an aluminum tubeset?
