Take extruded aluminum tube for example. This comes in two forms: structural and seamless. Structural extruded tube is made by the porthole process, and for that reason is sometimes referred to as “porthole.” Seamless is made by the seamless extrusion process.
In the aluminum industry, the porthole extrusion process is the standard method for the production of extruded tubes and profiles. The process is limited to a number of aluminum alloys. However, most of the commercially available medium strength aluminum alloys such as EN AW-6060 or EN AW-6082 can be extruded by porthole extrusion.
