Aluminum Tube
2024 aluminum tubing is heavily utilized in aircraft
applications due to good machining characteristics and higher strength than
either 2014 or 2017. Cold formability is considered fair, yet it is one of the
most popular alloys for high strength tubing requirements because of the
superior grain structure that can be obtained.
