There are many types of aluminum used in aircraft construction. One aircraft sheet metal used is 7075 aluminum. 7075 Aluminum is of high quality and offers high yield strength, toughness and ductility.
Tim Morris from Cincinnati State Community College offers another of his irreverent descriptions of aircraft sheet metal from the aircraft aluminum metal series.
Like many aircraft metals, corrosion protection is necessary on 7075. Despite its high cost it is a superior metal for aircraft construction. This video is intended for training Aircraft Maintenance Technicians (AMTs), Aeronautical Engineering Students or any others who may have an interest in understanding the many types of metals used in modern aircraft.
Hopefully the humorous approach will aid in learning this subject.
