[He blinks at her.] There are different kind of metals and they have different properties. For example iron, or steel or titanium. They have different properties and uses. For example aluminium is very low density which means that it is suibtable for building aircraft. Copper is a good conductor of electricity. Metals react differently to each other, for example some have a much higher melting point than others.
A lot of the metal used in the Tower was not like the ones I knew from my world. This metal was different again. It was not the same metal used to build robots in my world.
