Product description:

Reduced iron powder is aggregation of less than 1 mm iron. Is the main raw material of powder metallurgy. According to the granularity, customarily divided into coarse, medium and fine powder, fine powder and ultrafine powder five grades.Granularity is 150 ~ 500 microns within the scope of the particles of iron powder as the coarse powder, grain size between 44 and 150 microns for the medium powder, 10 ~ 44 microns for fine powder, 0.5 ~ 10 microns is very fine powder, less than 0.5 microns for superfine powder.General will 325 target quasi screen by particle size less than 44 microns powder called the sieve, if want to undertake higher precision screen divided we can only use air classification equipment, but for some easy oxidation of iron powder JZDF nitrogen protection classifier is used to do. Iron powder mainly include reduced iron powder and atomized iron powder, they are due to different ways of production and its name.


Once reduced iron powder

Production process:

(Iron Concentrate or rolling steel scale) → drying → Magnetic separation → shattered → screen → tinning → into once reduced furnace → get sponge iron.

Twice reduced iron powder

Production process:

Sponge iron → Brushing → broken → Magnetic separation → twice reduced furnace → powder blocks → break to powder → Magnetic separation →screen → grading → mixture → packing →get twice reduced iron powder.


Product application:

Reduced iron powder use in hard alloy,P/M,MIN,welding rod,electric conductive slurry,magnetic material,laser welding,diamond tools,high temperature alloy,rechargeable battery,the rubber and plastic injects products etc.


Product package: 25kg per bag, 40 bags in one 1000 kg jumbo bag.
