"Metal-based" refers to materials or compounds that primarily consist of metals or metal elements. These materials are often characterized by their strength, conductivity, and malleability. Common examples include alloys like steel and bronze, which combine different metals to enhance specific properties for various applications. In technology and manufacturing, metal-based materials are widely used in construction, electronics, and automotive industries. Their ability to conduct electricity makes them essential for components like wires and circuit boards. Additionally, metal-based coatings can provide protection against corrosion, improving the longevity of products and structures.
