The word "铜像" is formed by combining the character "铜", meaning copper or bronze, which uses the metal radical (钅) to indicate its material category and the component "同" primarily for phonetic indication, with the character "像", meaning statue or image, which uses the human radical (亻) to suggest likeness and the component "象" for both phonetic and semantic contributions related to form. Together, they create a compound where "铜" specifies the material and "像" denotes the object, resulting in the meaning "copper statue" or "bronze statue".
