Super fine iron powders are varieties of iron powders with particles smaller than 45 micron. Super fine iron powders vary in density, particle shape, flow-ability, purity, potential applications and price. All three types are fully magnetic
Here are 3 main types of super fine iron powders:
- Low Density, non-flow-able Super Fine Iron Powder with product code IRON325 consists of porous particles with irregular shape. This product usually contain about 98% iron, 1.5 percent iron oxide and less than 0.5% acid insoluble minerals.

This product usually contains about 99% iron, less than 0.13 percent oxygen and small amounts of carbon, sulfur, phosphor and SiO2.
Read more … - Very high density, high purity, free flow Super Fine Iron Powder with product code IRON325AT consists of solid-dense-high purity iron particles with wide range of particles mainly in the range of 15 to 45 microns. This product usually contains more than 99% iron and very small amounts of oxygen, carbon, sulfur, phosphor, titanium and SiO2. Read more …
