Iron Powder

Iron powder is made as an entire from several other iron particles. The particle sizes vary anywhere from 1-2 micron to around 850 microns depending on the process of manufacturing. The iron properties differ based onproduction method and history of aniron powder. There are various forms of iron powders classifications: reduced iron powder, atomized powder,electrolyte iron powder, carbonyl iron powders, cast iron etc Each type is employed in various applications based on their properties.

Iron powders are used to manufacture Nutritional supplements, Pharmaceuticals, Chemicals, diamond cutting tools, sintered components, soft magnetic components, brazing, friction products, printing, surface coating, chemical, oxygen absorbers, fertilizers etc.

The major factors that define the use of iron grade into specific applications are

1. Purity
2. Density
3. Particle Size Distribution
4. Particle shape
5. Reactivity
6. Impurity profile
7. Availability
8. Quality control and assurance system
9. Cost

Iron powder products are classified by purity, production method, grain and density.

Following are the foremost widely used iron powder products.
