Introduction
Tin bronzes and leaded tin bronzes are a group of copper alloys with UNS designation numbers starting at C90200 through to C94500. Bronzes are formed when copper is alloyed with tin as the primary alloying element. Bronzes have been in use since ancient times, and many variations are available in the market today. Some examples are commercial bronze, architectural bronze, and alpha bronze.
