How much aluminium in a Boeing 737?

A Boeing 737 is made up of approximately 75% aluminum by weight, which translates to around 20,000 to 25,000 pounds (about 9,000 to 11,300 kilograms) of aluminum, depending on the specific model and configuration. This lightweight material is essential for maintaining fuel efficiency and structural integrity in the aircraft. Additionally, aluminum's resistance to corrosion enhances the longevity of the plane.
