material classifications

Material classifications categorize substances based on their properties and uses. Metals are typically shiny, conductive, and strong, like steel and copper. Polymers or plastics are flexible, lightweight, and often used in packaging and everyday items. Ceramics are hard, brittle, and heat-resistant, such as porcelain and bricks. Composites combine materials to enhance performance, like fiberglass. Understanding these categories helps in choosing the right material for specific applications, considering factors like strength, flexibility, durability, and environmental impact.
