Non-metallic materials are substances that do not possess the characteristics of metals. They are typically poor conductors of heat and electricity, and they tend to be brittle rather than malleable. Common examples of non-metallic materials include plastic, glass, and ceramics. These materials are often used in various applications due to their lightweight nature and resistance to corrosion. In contrast to metals, non-metallic materials can be found in both natural and synthetic forms. Natural non-metals include elements like carbon and sulfur, while synthetic options encompass a wide range of polymers and composites. Their diverse properties make them suitable for use in industries such as construction, electronics, and packaging.
