What is Metal?

Metal is a solid material characterized by its strength, luster, and ability to conduct electricity and heat. It is typically malleable, meaning it can be hammered or pressed into different shapes without breaking. Metals are found in the Earth's crust and have been used by humans for thousands of years for various purposes.

Properties of Metals

1. Malleability: Metals can be hammered or rolled into thin sheets without breaking.

2. Ductility: Metals can be drawn into thin wires without breaking.

3. Conductivity: Metals are good conductors of both electricity and heat.

4. Luster: Metals have a shiny appearance when polished.

5. Strength: Metals are generally strong and have high tensile strength.

Types of Metals

There are two main types of metals:

1. Ferrous Metals: These are metals that contain iron, such as steel and cast iron.

2. Non-ferrous Metals: These are metals that do not contain iron, such as copper, aluminum, and gold.

Uses of Metals

Metals are used in various industries and for different purposes:

1. Construction: Steel and aluminum are commonly used in construction for buildings, bridges, and infrastructure.

2. Transportation: Metals are used in the manufacturing of cars, airplanes, and ships due to their strength and durability.

3. Electrical appliances: Copper and aluminum are used in wiring and electrical components due to their conductivity.

4. Coins and jewelry: Precious metals like gold and silver are used to make coins and jewelry due to their luster and resistance to corrosion.
