Iron+and+steel


 * “the old cast iron buildings died out. I'm not really sure whether the new skyscrapers killed them, or the new esthetics” **

I think it is true that the old cast iron buildings died out, but I think is because there are newer materials that work better than cast iron, have more strength in tension and compression, are cheaper and workable. For example we have other types of iron, steel and alloys such as stainless steel and aluminium that have much more benefits than iron cast.
