Iron is a relatively abundant element, pre-alloyed iron powder and the iron core is very stable. Iron is an important part of plant and animal life and a key component of hemoglobin. Pure metal iron is not often encountered commercially, and pre-alloyed iron powder is usually alloyed with carbon or other metals. Pure metal iron is chemically highly reactive and corrodes quickly, especially in humid air or high temperatures. Iron metal is a silvery, shiny metal with important magnetic properties.

Chemical properties: 99% to 99.95%; Physical properties: a) Almost all sizes and shapes and powder particles up to nanoparticles, b) Water atomization, flake, flake, sponge, spherical, irregular nanoparticles.

Typical applications: Iron powders are used in powder metallurgy of iron and steel and in combination with other metals. They are widely used in the automotive industry and in ferromagnetism.

Pig iron is an alloy containing about 3% carbon and containing different amounts of S, Si, Mn and P. It is very hard, brittle, and quite fusible. It is used to produce other alloys, including steel wrought iron, which contains a few percent of carbon. It is tough, tough, and not easy to fuse. It usually has a "fibrous" structure. A small amount of Mn, S, P and Si alloy steels are carbon steels containing other additives such as nickel, chromium, vanadium, etc. Iron is among all metals ^ cheap, ^ rich, ^ practical, ^ important.
