Elite: Dangerous PvE - Mobius

I have in my possession some meta-alloy in my cargo bay, give shout if need one. I had to traverse to Maia- Port Darneilles to re-purchase. Inadvertently sold mine at start of game, had no knowledge of engineers.

I'll keep alloys for a while in my bay, week or so.._.I have 8 at this time.
I'll be near Azrael this week, doing trade.

What do you use the Meta-Alloys for? I've been away in deep space for so long I haven't caught up to the updates.
