| General Man's search for tools and better materials to make them from has led him from the random use of pieces of wood, bone, and stone through the Bronze and Iron Ages to the Industrial Age. Along the way, man discovered many metal-working processes and uses for the finished metals. One of the earliest processes discovered was alloying copper with tin. This produced bronze and ushered in the Bronze Age. Practicable and economical ways to smelt iron ore and produce usable iron brought man into the Iron Age. Step by step, the way led to the Industrial Age. We now have many ways to process metal for particular uses. This section discusses some of these processes. The first three paragraphs are introductory; they define an alloy, classify alloys, and describe the ways of preparing alloys. The paragraphs that follow discuss, in more detail, the metal-working processes most commonly used.
