>>1902431Aluminium is widely used in alloys, so she'll get around a bit. She'll be an aviator of some kind, maybe even an astronaut, since aluminium's most famous use is in aerospace. I wouldn't put her quite at the age of Gold and Silver, but she's got a few years on Copper and Platinum. Middle generation, basically.
I'm currently leaning towards pairing her with scandium in the long run, since scandium's only real application is as an aluminium alloy. At the very least, scandium is her star-struck fangirl.
The other pairing option I see for her is beryllium, since the elements have similar properties due to a diagonal relationship and are both widely used in aerospace, but I sort of prefer the image of them as the sort of Top Gun very homo friendship rather than a straight-up romance.
>>1902433I still have no idea how to handle most of the nonmetals, past maybe C (mentioned) and Si (one of Copper's computer nerd friends). I'm sticking to metallics for now, anyway.
