The problem with iron at this level of purity is that it is too soft and too ductile for most commercial uses.
Physics trivia: Iron is the heaviest atom that can be made by the fusion of stars. Iron is is the ‘ash’ of stellar nuclear fusion. Iron is abundant- the fifth most abundant element on earth, and sixth most abundant in the universe. Our blood is red because of iron, and since iron is an essential part of our bodies, we can truly claim that we are “Stardust.”
Iron is essential to almost all living things indeed it is key to the working of hemoglobin and oxygen transfer in humans, as well as in enzymes that are involved in the creation of DNA.
Our bodies store surplus iron in the liver, to cover for those days when we do not get our required 7 to 11 milligrams of daily iron.
When properly contaminated with carbon, manganese, a sprinkle of sulfur or phosphorous, iron makes some damn fine precision machined parts too!
*I was originally taught= Alloying Elements in Steel by Edgar C Bain and Harold W Paxton, 2nd edition:
“The metal iron, as shown in figure 1., exists in two isometric allotropic crystal forms: (1) alpha and delta iron, whose solid solutions are called ferrite (or delta ferrite) and (2) gamma iron whose solid solution is is austenite.”
