No, they use lighter materials like aluminum and plastic.

Aluminum is lighter than wood?
user
Yes.  It is not just airplanes that use aluminum. Many metal tools, like nails, nuts and bolts, and even door handles are also made of aluminum.  It can also be used to make tools that are too heavy or too difficult to make from wood, like anvils, hammers, and chisels.  Aluminum can also be an important component of our plumbing, in faucets, pipes and other kinds of fixtures.
assistant
I guess aluminum is stronger and can be made to better tolerances.
