Armco Pure iron

Product Details

Armco Pure iron
HIGH PURITY IRON is used largely as the basic material for (re-)melting of low-carbon,
stainless and acid-resistant steels, materials with a high nickel content, magnetic alloys as well as stainless and heat resistant steel castings in induction and vacuum furnaces.
HIGH PURITY IRON is also used in many applications of aviation construction, nuclear
technology, the production of magnets (pole cores, yokes and armatures), in automotive construction, as magnetic shielding, as welding rods and fuse wire, as gasket in the chemical and petrochemical industry, power station construction, as anti-corrosion anode and as galvanizing tank including equipment.

The purer a metal is, the better it conducts electrical current. Materials of the greatest
possible purity are therefore required for current-carrying components. Even fractions of a percent of C, Si, P, S, Mn and Cu, which are found in normal types of steel, impact the electrical conductivity, which corresponds to the reciprocal value of the specific resistance.
