What is tin for?

[coolpete21]

Well I am ranking up metal conversion.... and I stumbled upon tin. I waited a couple of rank ups (now r9) and realized there is no recipe using this. I also stumbled upon Zinc and nickle. I was wondering what this is for.

No use as of yet. According to MabiJP wiki, they even have no use for it, and I think they're a generation ahead of us.

I'm holding onto mine. Maybe it'll have a use later.

<Sidenote>Converted ~2000 iron ingots yesterday. I have enough nickel to supply the treasury for a decade. I hope they add a use soon
