Common Materials Used To Make Gears

For an in depth look at some of the most common materials used to produce gears, click here. Steal, bronze, plastic, and cast iron are all mentioned.


The common materials used to make gears are extremely important. Not only does the material play a vital role in the engineering of the gear, but also the gear design as well. To take a closer look at the different types of materials that are used, continue reading the content below.  


What better material to start with than the most commonly used option? Not only is the strength-to-weight ratio incomparable, but steel is extremely durable and resistant to wear and tear. Its ability to handle extreme heat is also impressive. Most impressive of all, though, is the fact that steel isn’t too costly compared to its competitors.


One can also refer to this specific gear material as copper alloy. This material is unique in its ability for minimal wear and use for for gear reducers. Typically, worm gears are often made out of bronze material.


Plastic gears are often made out of nylon and acetal. However, nylon does absorb moisture which unfortunately can result in the properties and dimensions of the gear changing. Nylon also can’t withstand extreme temperatures or pressure, which puts it at a great disadvantage. Yet, some specific applications still end up having nylon as the choice material for the gears.

Cast Iron

This material is known for its ability to bear high pressure and can withstand low or high temperatures. It also has extremely low wear resistance and a high mobility level. Although, it unfortunately has a poor casting ability.

There are other common materials used to make gears. However, the four mentioned above are the most popular options. The material that the gear will be made out of will depend on how you’ll apply it.
