This article discusses the composition, properties, and behaviors of copper and its alloys. It begins with an overview of the characteristics, applications, and commercial grades of wrought and cast copper. It then discusses the role of alloying, explaining how zinc, tin, aluminum, silicon, and nickel affect the physical and mechanical properties of coppers and high-copper alloys as well as brasses, bronzes, copper-nickels, and nickel silvers. It also explains how alloying affects electrical conductivity, corrosion resistance, stress-corrosion cracking, and processing characteristics.

This appendix contains tables listing the approximate composition of materials for the extrusion process. The materials covered are aluminum alloys, magnesium and magnesium alloys, copper and copper alloys, cobalt alloys, nickel and nickel alloys, iron alloys, steels, lead, tin, zinc alloys, molybdenum, niobium, tantalum, zirconium alloys, titanium, and titanium alloys.

The term heat treatable alloys is used in reference to alloys that can be hardened by heat treatment, and this chapter briefly describes the major types of heat treatable nonferrous alloys. The discussion provides a general description of annealing cold-worked metals and describes some of the common nonferrous alloys that can be hardened through heat treatment. The nonferrous alloys covered include aluminum alloys, cobalt alloys, copper alloys, magnesium alloys, nickel alloys, and titanium alloys.
