The Utilization of Extrusions for Aerospace Applications

Metallic extrusions are used by the aerospace industry for structural applications in both aluminum- and titanium-alloy systems. The utilization of extrusions can lead not only to better buy-to-fly ratios, but additionally increased performance over other product forms in certain applications when properly leveraged. Due to their higher flow stresses and more complex metallurgical processing routes, the technologies used in the manufacturing of structural aerospace grade extrusions differ from those of automotive or architectural products. This presentation will cover the fundamentals of aluminum and titanium extrusions, discussing the differences in extrusion technologies depending on the alloy and application, the various paths to making hollow extrusions, the complexities of thick gauge “heavy” aluminum extrusions and the developments in complex titanium extrusions. Additionally, advances in aluminum alloy technology will be presented.
