Advantages of powder metallurgy reducing iron powder

The reduced iron powder of sponge powder has irregular pores and moderate compressibility. It has been used in the production of powder metallurgy parts for more than 70 years. Its advantage is that it is irreplaceable to use sponge iron powder to make powder metallurgy heavy load parts, and it still plays an important role in friction structural parts and oil-bearing self-lubricating bearings.In powder metallurgy applications, such measures as decarburization of powder particles and grinding and refining of high-carbon powders are commonly used to improve compressibility.
