Other Nonferrous Alloys
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 article examines the role of alloying in the production and use of nickel and its alloys. It explains how nickel-base alloys are categorized and lists the most common grades along with their compositional ranges and corresponding UNS numbers. It describes the role of nearly 20 alloying elements and how they influence strength, ductility, hardness, and corrosion resistance. It also addresses processing issues, explaining how alloying and intermetallic phases affect forming, welding, and machining operations.
