ARMCO iron

Technically pure iron with a Fe content of 99.8 - 99.9 % and a low carbon content.

It is used as melting material in electric furnaces (mainly in vacuum furnaces) for the production of low-carbon, non-corroding, non-magnetic or heat-resistantcast steel. It is a soft and tough material with low coercive force, high magnetic saturation, good electric conductivity and high corrosion resistance due to its purity. It was developed in 1909 by what was then the American Rolling Mill Company (ARMCO).
