Does any one know the alloy used for the stock triple trees on the tube frame bikes? | ||

My 97 S1 polished up like straight cast aluminum. Not sure of the exact content. Hope that helps some. | ||

lol not really but thanks for trying i just have a chance to get my hands on a block of 2024 alloy and i was wondering what alloy is used in the triple trees. i know very little about metals as I'm still working on my education | ||

It would be interesting to know what the composition is for the aluminum in the triple trees... I'd probably guess A356... If you have 2024 and you heat treat it to condition T6 or T861, it's very strong (for aluminum). Probably much stronger than what was used for our triple trees. However, if you have 2024 and it is in the annealed state (no heat treat), it is going to be relatively weak. Take a look at www.matweb.com to get an idea of material properties for different grades of aluminum, specifically the yield strengths. | ||

thank you devil, its research time  | ||

I know from the man that A356 is what the wheels are. | ||

I'm no metallurgist... But since, as all the tubers I've seen, which is not a lot at all, and all later models, the stock trees are castings. From the looks of them, and the clean cut off the trim die, I'd guess they were die cast. But they also may have been investment casr. Different alloys for each process. My point is the type of alloy you get in order to machine from solid is bound to be different from casting alloys. I'm not knowledgeable to make a suggestion as to type. Be a fun project, though.
