So I came across this little piece of metal today. For some reason it says that I am not allowed to post links yet, so I will just have to describe it to you as best I can.



The exterior of the metal is dull grey I color. It is non magnetic. The metal is rather brittle, and when broken it reveals a bright, sparkling, silver interior with a grainy texture. It reminds me a lot of what ferrite looks like when broken except that this metal is not magnetic. Any ideas as to what this could be? Thanks in advance!
