Engineering Materials

Engineering materials refer to a variety of materials used for manufacturing engineering structures and components. They are widely applied in fields such as mechanical engineering, construction, electrical engineering, and aerospace. Based on their composition and properties, engineering materials are generally categorized into four main types: metallic materials (e.g., steel, aluminum), ceramic materials (e.g., alumina, silicon nitride), polymeric materials (e.g., plastics, rubber), and composite materials (e.g., carbon fiber-reinforced plastics). When selecting engineering materials, factors such as mechanical properties, corrosion resistance, thermal performance, and cost-effectiveness must be considered to meet specific application requirements.
