What are the characteristics of powder metallurgy parts?2

   Powder metallurgy alloy tensile strength, toughness and ductility with increasing density will increase, may also improve the workability, this is because the porous harmful effect on the nose. The sound insulation performance of the parts is enhanced with the holes rate, and the general damping oscillation of the standard parts is reduced in the powder metallurgy parts. This is very important to the machine tool, air conditioning duct and pneumatic tools, high porosity of the self lubrication gear is also necessary.
