Stronger.





to Powder Metallurgy (P/M)



Low standard mechanical properties (e.g. tensile strength) are typical of P/M parts. The grain flow of a forging ensures strength at critical stress points.






Higher integrity.








Costly part-density modification or infiltration is required to prevent P/M defects. Both processes add cost. The grain refinement of forged parts assures metal soundness, absence of defects.








Fewer secondary operations required.








Special P/M shapes, threads and holes and precision tolerances may require extensive machining. Secondary forging operations can often be reduced to finish machining, hole drilling and other simple steps. The inherent soundness of forgings leads to consistent, excellent machined surface finishes.








Design flexibility.








P/M shapes are limited to those that can be ejected in the pressing direction. Forging allows part designs that are not restricted to shapes in this direction.






More cost-effective.








Long production runs are often required to recoup initial P/M tooling investment. New P/M parts require long lead times. Forging can respond quickly to changes in product demand and remain cost effective once die tooling is available at the forge.








Broad supplier base.








P/M supplier base is limited. The comparatively larger number of qualified forgers ensures best possible service.
