Aluminum, more than any other material, has the ability to be extruded into complex shapes to exact tolerances. Other metals such as steel can be extruded. However, they require enormous pressure to pass through the die. This makes all but a few simple extrusions uneconomical.
The fact that aluminum material can be extruded more easily provides the opportunity to use this metal in every field.
Thanks to this feature of aluminum material, it is possible to achieve success in extremely complex product and system designs.
