The hardness can reach to HRC30~40 or even higher after sintering. The material is good for part need higher hardness, but don't need and can't be secondary operation (machining)
Versatility
Practically any desired metal, alloy, or mixture of metals can be produced in this way
Self-Lubrication
This feature is unique to powder metallurgy parts. The controlled network of small pores in the parts can be filled with oil or other desirable lubricants selected for contact with any variety of wearing surfaces.
Economy
It is an economical process because of the rapid, mass production techniques employed, the reduction or complete elimination of subsequent machining or finishing.
Intricate Shaped Parts
Powder metallurgy is ideal for the production of unusual or complex shaped parts that are almost impossible or impractical to obtain by other methods.
High dimensional accuracy and good surfaces.
High Strength
Choosing the suitable material, form sintering and optional manufacturing steps, high tensile strength can be made.
