ARMCO Steel

ARMCO marked electrical steel is refined iron. The abbreviation comes from the name of the company – American Rolling Mill Corporation, which first offered customers commercially pure iron. The main difference between ARMCO steel and analogues is the almost complete absence of foreign impurities in the composition.

As a rule, ARMCO steel marking implies the presence of foreign impurities in volume composition is not more than 0.1%. The mass fraction of carbon in this case is not more than 0.02%.

Alloy features

This type of alloy has an increased resistance to corrosion processes of any type. ARMCO steel is characterized by maximum electrical conductivity, while it is quite ductile and not brittle.

Such properties of alloys have made it possible to find a fairly wide range of applications for steel. It is used in the production of electromagnetic cores, various components of current relays. In addition, the alloy itself is one of the components for the manufacture of magnetic alloys of complex composition with specified parameters and properties.

cause of eddy currents. This must be taken into account when creating magnetic circuits and relays.
