Iron (Fe) Powder

Physical and chemical properties:

Iron powder is an aggregate of iron particles with a size of less than 1mm. It is the main raw material of powder metallurgy. There are five grades of coarse powder, fine powder and superfine powder. The particle size is 150 ~ 500 μ The iron powder composed of particles in the range of M is coarse powder with a particle size of 44 ~ 150 μ M is medium powder, 10 ~ 44 μ M is fine powder, 0.5 ~ 10 μ M is very fine powder, less than 0.5 μ M is ultrafine powder

generally, it will be able to pass the 325 target standard sieve, that is, the particle size is less than 44 μ M powder is called sub sieve powder. If higher precision screening is required, only air flow classification equipment can be used, but for some easily oxidized iron powder, only jzdf nitrogen protection classifier can be used. Iron powder mainly includes reduced iron powder and atomized iron powder, which are named because of different production methods

Purpose:

Iron powder is mainly used to produce powder metallurgy mechanical parts. Its main physical properties are loose density, fluidity, formability, particle shape, etc. these properties are mainly affected by the Iron powder is mainly used to produce powder metallurgy mechanical parts. Its main physical properties are bulk density, fluidity, formability, particle shape, etc. These properties are mainly affected by the production method of iron powder and its chemical composition.

(1) Application of hinge powder in the manufacture of powder metallurgy structural parts

The use of powder metallurgy to manufacture mechanical parts has the advantages of saving materials and man-hours, easy automation, and easy organization of mass production, which has attracted widespread attention and has developed rapidly. Iron-based powder metallurgy machinery parts have been widely used in my country's automobiles, motorcycles, household appliances, power tools, office machinery, agricultural machinery, machine tools, instrumentation, textile machinery, metallurgical machinery and other industrial sectors, and have achieved good technical and economic benefits .

(2) Application of iron powder in electrode production, flame cutting, etc.

Iron powder for welding rod occupies a certain proportion in the whole application of iron powder (Sweden accounts for 37%). Generally, adding 10% to 30% of iron powder to the coating of the electrode can improve the welding performance of the electrode
