Engineering Materials and Classification

Engineering materials are classified into metals, polymers, ceramics, and composites, each with distinct properties and applications. The properties include physical, mechanical, thermal, electrical, chemical, and economic factors that influence their suitability for various use cases. Standards for material designation aid in identification and selection based on performance and cost considerations, utilizing methods like Ashby Diagrams for material comparison and selection.
