Metallic

Metallic refers to substances that exhibit the properties of metals. These properties include high electrical and thermal conductivity, malleability, ductility, and a characteristic luster. Metals are typically solid at room temperature, with the exception of mercury, which is liquid.

Properties of Metallic Substances

Metallic substances are characterized by their unique set of properties:

• Electrical Conductivity: Metals are excellent conductors of electricity due to the presence of free electrons that can move easily through the lattice structure.
• Thermal Conductivity: Metals can efficiently transfer heat, making them useful in applications requiring heat dissipation.
• Malleability and Ductility: Metals can be hammered into thin sheets (malleability) or drawn into wires (ductility) without breaking.
• Luster: Metals have a shiny appearance due to their ability to reflect light.

Types of Metals

Metals can be broadly classified into two categories:

• Ferrous metals: These metals contain iron. Examples include steel and cast iron.
• Non-ferrous metals: These metals do not contain iron. Examples include aluminum, copper, and zinc.

Applications of Metals

Metals are used in a wide range of applications due to their versatile properties:

• Construction: Metals like steel and aluminum are used in building structures, bridges, and infrastructure.
• Electronics: Metals such as copper and gold are used in electrical wiring and components.
• Transportation: Metals are used in the manufacturing of vehicles, aircraft, and ships.
• Jewelry: Precious metals like gold, silver, and platinum are used in making jewelry.

Related Concepts

• Alloy: A mixture of two or more elements, where at least one is a metal, to enhance properties.
• Corrosion: The process by which metals deteriorate due to chemical reactions with their environment.
• Metallurgy: The science and technology of extracting metals from their ores and modifying the metals for use.
