I've never seen pure solid tin as plates. Tin is soft so its 
not very good for making things. Try your local chemical 
company for tin metal, if not then plating suppliers or 
metal merchants. I got mine from a metal merchant. They had 
them in various ingots 0.5 to 2 kg. Look up metal suppliers 
in your local business directory. I found trying to find 
supplies is a matter of making enough phone calls and asking 
the right questions. Remember these people are in this line 
of business and would know a lot more than you of what's 
around and who is selling what and where.
