Question

why iron is not used in pure state?

Answer 1

Pure iron oxidizes (rusts) rapidly and is soft as well as strongly magnetic.Therefore it is of little use. On alloying it with small amount of carbon, the strength of iron increases and thus it can be used for making different articles.Similarly different alloys of iron have different uses.

Answer 2

Heya mate
your answer is

Pure iron is soft and very malleable and is able to stretch a lot and it is also ductile. It can rust (oxidize) readily in moist air. It is also fairly reactive. Pure iron has little use - some for analytical chemistry and some in medicine. It is made much more useful by alloying it with other materials. due to these drawbacks iron is not used in pure state.

Hope you satisfied with my answer...
