Military/AirHigh strength with light weight, minimal maintenance, the absence of brittleness at low temperatures, and the ability to engineer a wide range of functionality into components, make aluminum extrusions a major element of military, aircraft and aerospace solutions.
And aluminum has played an important role in these applications for years; in fact, the Wright Flyer, in which the Wright Brothers achieved the first powered flight in December 1903, utilized a cast aluminum engine block to minimize weight. Today, a new generation of aluminum-lithium alloys for extrusions and forgings is offering aircraft producers weight and fuel savings vs. the newest composites.
Today you'll find aluminum extrusions in:
