Hi Brevven,
Thanks once again for all your mods.
Just a suggestion from my side: as a lot of aluminium-lithium is currently used in aerospace industry, I would suggest to add it in your mod (you have often copper and zirconium in these alloys also).
These alloys are really light, and so well suited for aerospace needs.
If I remember well, you do not use K2 lithium for your alloys recipes so far.
However, I don't know how to integrate it in the game, perhaps for low density structures (if not too complex for utility tech cards) ? Or I was also thinking about (new ?) parts to launch rockets.
What are your thoughts ? :)
