Traditionally, pewter is composed of about 85-99% tin. The remaining percentage consists of other metals such as copper, antimony, bismuth, and sometimes small amounts of other elements such as lead or silver. These additional metals are added to change the characteristics of the tin alloy and enhance its properties.
