An aircraft extrusion is a piece of aluminum alloy metal that is heated up and either pushed or pulled through a die. This process creates shapes with sharp corners like the ones shown on the chart below starting with BAC 1503, BAC 1504, or BAC 1505.

It is easy to confuse aircraft extrusions with related materials such as rolled sections or stringers because the part numbers are similar, but a formed or rolled section of aluminum alloy does not produce a sharp edge.

Formed shapes and rolled sections are different because they start with a flat sheet of aluminum alloy that is either brake formed or rolled into a desired shape, but it cannot be made into a T shape like you get with extrusions.

So, for example, you can see the typical shapes below on our chart for formed sections, including BAC 1490, BAC 1493, and BAC 1498, which have part numbers that are similar to aluminum extrusions, but are produced through a very different process.
