What was the Apollo 11 lunar module made of?

The Apollo Lunar Module, also known as the Lunar Module or LM, was primarily constructed using aluminum alloys. The external structure, including the landing legs, ascent stage, and descent stage, was largely built from aluminum alloys such as 2219 and 7075. These alloys provided a combination of strength, durability, and lightweight properties essential for a spacecraft designed to land on the lunar surface.
