Abstract
Iron ordinarily has a density that in the context of aluminium, silicon, magnesium and lithium is large. It nevertheless has properties that are so superior that the quantity of iron used exceeds that of all other metals combined by a very large amount. However, there are specific engineering applications where it would be a tremendous advantage to have all the properties of iron but at a smaller density. The methods available for achieving this goal are described here. There has been substantial progress and some low-density iron alloys are now commercially available.
