Does Aluminium Contain Iron?

Aluminium is one of the most versatile metals used in modern manufacturing. It’s lightweight, strong, and resistant to corrosion, making it ideal for a wide variety of applications. But does this metal contain iron? Let’s take a closer look at how aluminum is made and determine if it does contain iron.

How Aluminium Is Made

Aluminum is made from bauxite ore which is found naturally in nature. Bauxite ore contains various minerals, including iron, silica, and titanium dioxide, among other elements. To produce aluminium from bauxite ore, the ore must be refined and heated in an electrolytic process that separates the aluminum from the other minerals. This process does not add any iron to the aluminium; rather, it removes any trace amounts that were present in the raw bauxite ore.

Types of Aluminum Alloys

The high strength-to-weight ratio of aluminium makes it a great choice for many industrial applications, such as aerospace engineering, automotive components, and consumer electronics. While pure aluminum can be used for some applications, most manufacturers use alloys which are a combination of two or more metals with added properties such as strength or malleability. It should be noted that some alloys do contain traces of iron depending on what is added during production to create particular desired effects. However, no type of alloyed aluminium contains enough to be considered ferrous metal – meaning its content isn’t enough to trigger a magnetometer test for security purposes at airports etc.


To conclude – yes, some types of aluminum alloys may contain traces of iron, but overall pure aluminum does not contain iron. In addition to being lightweight and resistant to corrosion, pure aluminum also has higher thermal conductivity than alloyed versions, which makes it ideal for certain types of electronics and appliances (such as cell phones). No matter what your application is, though – you can rest assured that pure aluminum will not contain any significant amount of iron!
