The first heat of ARMCO® Pure Iron to be produced in Europe was cast in Germany at 'Vereinigte Stahlwerke AG'. In 1957 ARMCO® Telar 57 was developed as a non-aging variant of ARMCO® Pure Iron, in order to satisfy the specific needs of the electrical industry. After a century of technical progress, ARMCO® Pure Iron, because of its special properties, is still a very modern and widely used material satisfying various requirements of many of today's demanding industries. Its unique characteristics in numerous applications ranges from remelting to electromagnetic components and various delivery forms from remelting billet to pyrometer protection tubes are described on the following pages. AVAILABLE PRODUCTS Characteristics Chemical Composition Applications Delivery Program Characteristics ARMCO® Pure Iron: Purest iron ever produced, Fe = 99.85% Homogenous structure of pure ferrite containing exceptionally low level of carbon, oxygen and nitrogen, combined with a low incidence of non-metallic inclusions Compared with mild steels the high purity results in a number of advantages such as: Better resistance to corrosion, oxidation and chemical attack Excellent electrical and magnetic properties Excellent cold working properties Excellent weldability ARMCO® Telar 57: Soft magnetic iron providing excellent resistance to magnetic aging effects High magnetic flux density Low coercive force Chemical Composition ARMCO® Pure Iron Grade 1* Grade 2 Grade 3* Grade 4 % max. max. max. max.
