Iron+&+Steel



=Iron and Steel, About lab materials.=

Comparing with others materials, i think that the iron and the steel are stronger that them, in particular i think that the steel y the strongest and also is more flexible than the iron. I can say that the iron is maybe heavier than steel, but that could be a disadvantage, because it could be difficult to transport it.

=1. Find the meaning of "Wrought Iron" and its uses=

Acording to the virtual encyclopedia Wikipedia, wrought iron is an iron alloy with a very low carbon content, in comparison to steel, and has fibrous inclusions, known as slag. This is what gives it a "grain" resembling wood, which is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile and easily welded. Historically, it was known as "commercially pure iron", however it no longer qualifies because current standards for commercially pure iron require a carbon content of less than 0.008 wt%.

It could be used to make furniture, doors, and others elements of the dwellings. Also in the world there are others stuffs made of whought iron, an example of that is the eiffel tower, wich is a tower that works as a landmark in Paris city.



**2. Answer: Do you think metals are "cold" materials?** **Explain**


 * I think that the metals could be considers cold materials, but that is beacuse they are conductors of temperatures and then they the most of the time are colds. If the earth's climate was much warmer, the metals was too. So, that's why they could be consider like "cold" materials.

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

In believe that it is totaly true, in my opinion, the ol cast iron buildings died out because of the new ideas about construction, maybe because of the skycrapers too, I mean they belong to the new wave of ideas about constructions and design. This old bast building has not any esthetics, nowadays we can not think in them like a solution for living because there are new solutions for that that the architecture and the design have been doing.
