Powdered Metal Gears

Custom Powder Metallurgy Gears

Powdered metal gears are made through the process of powder metallurgy. There have been many advances to this process over the years, which have in turn caused an increase in the popularity of powdered metal as a gear material.

Powdered metal gears are used in many industries, but are used most in the automotive sector. Typical automotive applications include engine parts such as sprockets and pulleys, gear shift components, oil pump gears, and turbocharger systems. Powder metallurgy can be used to produce spur gears, helical gears, and bevel gears.

What is Powder Metallurgy?

Powder metallurgy is a process for forming metal parts. There are three steps in the process:

1.Mixing the metal powders

2.Compacting the powders to the desired shape 

3.Heating the compacted shape under controlled conditions

The end result is a metal part that is nearly identical to the desired shape and requires little or no machine finishing, depending on the level of precision needed.
