Er no... There are lots of iron meteors out there. Here are a few that have impacted the earth:
Largest iron meteorites found on Earth not have craters?
Ambassador Greg Shanos and iron meteorite at McDonald Observatory.
Er no yourself. more meteorites are mostly iron because the carbonaceous chontrites (rocks) don't survive the journey through the atmosphere very well.
Being generous here say 10% of all asteroids are solid nickel iron. A. nickel and iron aren't all that valuable and B. What do you do with them once you get them into orbit assuming that they don't come crashing down and flatten the odd city?
You can make structural steel out of them. ANy idea how much mass a steel fabricating plant plant represents?
