What is an Alloy?

       An alloy is a substance composed of two or more metals, nonmetals, or possibly gases that are mixed by fusion, dissolving, melting or mixing.

Examples of Alloys:

• Bronze- Bronze is made when Tin and Copper are combined.  Bronze was commonly used in the Bronze Age for technology.  Cruder forms of Bronze can be made by combining Copper with Aluminum, Silicon, Manganese, or Phosphorus.
• Steel- Steel is made when Iron is combined with a small amount of Carbon.  Steel is popularly used in buildings or as reinforcements for more unstable items such as concrete.
