Does anyone know what type of aluminum alloy (or aluminium) is used for the unibody? That is, what is the Aluminum Association alloy number?

    I don't know, maybe a 18-8? I really don't know and I don't think most people do.

    Unless Apple has released that specification, and I don't believe they have, no one here would know. This is a user-to-user forum. Is there an easy way to test it?

    I never really thought about what aluminum was used for the MacBook but after looking close it appears to be 2024 T3. I have been a aircraft mechanic for 35 years but what it appears and what it is can be totally different with something like the MacBook. I do doubt that it is anything stronger as it would then run into being brittle.

    When you do anything stronger if it is dropped it might get cracking.

    so i have been working in a machine shop for over 2 years now ive dealt with a ton of aluminum lately and im gonna have to say its one of the most common aluminum used which is 6061 t-6 its easy to make parts out of and very durable and not to costly but still not cheap. that 2024 t3 isnt as formable and very pricey. it would be nice to know that there spending a ton of money on it but im guessing due to how easy and cheap it is for 6061 that is gonna be your best bet.
