Alcoa aluminium is no doubt used in Tesla frames that are stamped out by massive hydraulic presses.
Saw somewhere that they are so strong they demolished the crash test equipment,
Only problem with Teslas is that the batteries catch fire sometimes,
So nice pure HPA is part of the answer (having super pure Li the other important aspect).
Guess its easiest to go with a current supplier!

Yep,5Kg of HPA is the figure that Tesla gave,multiple that by production current and future and you'll know what we're dealing with folks.
So even if a 50:50 JV, we are looking at multiples of the current SP.
