About iron powder
It is an aggregate iron powder and the size is approximately 20-200 microns. It is used as a particle size distribution and apparent density etc , and the character changes by production technique or past record.
It is a technique to make materials and products by forming and sintering metal powder or mixture of metal powder and non-metal powder. And the product is called sintered parts. They are used for automotive component mainly. Sintered parts get many empty holes when the process of compounding the powder, and density of the parts change by quantity of empty holes therefore the mechanical property such as strength changes.
Ex. Bearing, filter parts, magnetic material, machine parts, friction material, high intensity/ wear resistant parts
