Engineering Performance Matrix
Material Classification is the process of cataloging solid materials by their atomic and molecular characteristics and properties to aid in the selection of a suitable material for a particular application as well as the processes necessary for manipulating the materials in a suitable manner. This core concept includes knowledge related to the micro and macro-structures of the four main divisions of the material class system which are (a) metals/alloys, (b) polymers, (c) ceramics, and (d) composites. Material Classification is important to the practice of Material Processing as engineering professionals must consider material properties in order to make informed decisions when selecting and applying the most appropriate materials for the production of technological products and systems. Material selection is based on fabrication requirements, such as the material’s machinability, castability, and weldability as well as its intended final shape, required mechanical properties, service necessities, tolerances, availability, and the cost.
