I need the material specs on Chinesium; I can't find it in my periodic table. Maybe it's a homebrew metal?
No, its there. Listed right underneath 'unobtanium'.
All kidding aside...."Chinesium" = Any substandard metal for the purpose required. I.E. where the use of say 'Magnesium' would be appropriate/common....'pot metal' is used instead. And so forth.
