Is pig iron pure?

Traditionally, pig iron was worked into wrought iron in finery forges, later puddling furnaces, and more recently, into steel. These are high purity pig irons and depending on the grade of ductile iron being produced these pig irons may be low in the elements silicon, manganese, sulfur and phosphorus.

What is pure iron used for?

Pure Iron is largely used in the production of relatively small volumes of special alloy steels, in the aviation, automotive, construction, petrochemical industries, and in the manufacture of magnets, gaskets, fuse wire, welding rods, lighting conductors and MRI scanners.

What does pure iron look like?

Pure iron is a bright silvery-white metal which oxidizes (rusts) rapidly in moist air or in water containing dissolved oxygen. It is soft, malleable, and ductile, and is strongly magnetic (ferromagnetic).

Can you make pure iron?

As a raw material for smelting various special alloys such as superalloys, heat-resistant alloys, precision alloys and maraging steel, technically pure iron has been widely used in metallurgical industry. Technically pure iron is produced by pyrometallurgy.

Why is pure iron not used?

Answer. Pure iron is not used for making permanent magnets because it loses its magnetism easily. Carbon steel is used to make permanent magnet. In order to convert a material electrically into permanent magnet it is placed inside a solenoid.

Can iron be used to make a permanent magnet?

In its natural state, steel isn’t magnetic, but it can be modified in a way that turns it magnetic. Steel isn’t the only material used to make permanent magnets. Permanent magnets are also made of ceramic, iron, cobalt, nickel, gadolinium and neodymium.

Why iron is not suitable for making permanent magnets?

Iron is not suitable for making a permanent magnet Materials for making permanent magnets should have high coercivity so that magnetization is not erased by stray magnetic fields, temperature fluctuations or minor mechanical damages. Soft iron/pure iron has much smaller coercivity.
