About the Statue of Liberty. What materials make up the Statue of Liberty? The Statue of Liberty is made of copper 3/32in. (about 2.5mm) thick, the same as two American pennies placed together. The internal structure is comprised of cast iron and stainless steel. Why is the Statue green? The Statue's copper has naturally oxidized to form the outer patina, or green, coating. Upon completion in 1886, the Statue of Liberty was more of a traditional brown color, like an American penny. It took about thirty years for the Statue of Liberty to fully oxidize and form the patina.
