This article reviews the production variables that influence the selection of various stamping die materials: ferrous, nonferrous, and plastic die materials. It provides a discussion on the specific types of die materials for tool steels, cast irons, plastics, aluminum, bronze, zinc-aluminum, and steel-bonded carbides. The article describes factors to be considered during the selection of materials for press-forming dies.

Ceramic-metal composites, or cermets, combine the heat and wear resistance of ceramics with the formability of metals, filling an application niche that includes cutting tools, brake pads, heat shields, and turbine components. This article examines a wide range of cermets, including oxide cermets, carbide and carbonitride cermets, boride cermets, and other refractory types. It describes the powder metallurgy process by which cermets are produced, examining each step from powder preparation to post treatment. It discusses forming and compacting, injection molding, extrusion, rolling, pressing, slip casting, and sintering. It also discusses fundamental concepts such as chemical bonding, chemical composition, microstructure, and the development of physical and mechanical properties.

Cermets are a group of powder metallurgy products consisting of ceramic particles bonded with a metal. This article describes the composition and microstructure of titanium carbide and titanium carbonitride cermets. It tabulates typical properties of titanium carbonitride cermets and compares the properties of cermets and cemented carbides. The article also summarizes the applications of cermet cutting tools.

Ceramics are materials with the potential for a wide range of high-speed finishing operations and for high removal rate machining of difficult-to-machine materials. This article describes the production process, composition, properties, and applications of ceramic tool materials. It presents a comprehensive discussion on the properties and composition of alumina-base tool materials, including alumina and titanium carbide, alumina-zirconia, and silicon carbide whisker reinforced alumina, and silicon nitride base tool materials.
