there should be a metals section with things like steel- does't conduct electricity, melts at high temp iron- same as steel but "rust" with contact with water and when iron is melted it turns to steel when it cools titanium- stronger than steel but same properties aluminum- very weak and low melting point gold- weak, low melting point, conducts electricity silver- weak, lower melting point, conducts electricity very easily copper- very weak, low melting point, conducts electricity
(even though they all conduct electricity it would be cool for the few i mentioned to "not" conduct, mostly because steel, iron, and titanium dont conduct AS WELL AS silver, or copper in reality)
