It's mostly copper cladding, but there are also "small amounts of copper alloys, such as copper-zinc and copper-tin," to give variation. That quote came from the "Architect's Statement." Unfortunately, there was nothing in the statement about whether those have been treated to stay that color or whether they'll age and change to a green patina. It seemed like I read previously that they would age, but now I can't remember.
