Iron dust is a collection of iron particles less than 1mm in size,
iron dust, which is an aggregate of iron particles with a size of less than 1mm, is the main raw material for powder metallurgy. According to the particle size, it is traditionally divided into five grades of coarse powder, medium powder, fine powder, micro-fine powder and ultra-fine powder. Iron powder composed of particles with particle size in the range of 150~500μm is coarse powder, particle size in the range of 44 ~ 150μm is medium powder, 10 ~ 44μm is fine powder, 0.5~10μm is extremely fine powder, and less than 0.5μm is ultra-fine powder.
