Metal is a solidmaterial that is typically hard, shiny, and has good electrical and thermal conductivity. It is usually malleable, which means it can be hammered or pressed into different shapes without breaking.
Types of Metals
There are two main types of metals: ferrous and non-ferrous. Ferrous metals contain iron, such as steel and cast iron, while non-ferrous metals do not contain iron, such as copper, aluminum, and gold.
Properties of Metals
Metals have several important properties, including:
Conductivity: Metals are good conductors of electricity and heat, making them useful in electrical wiring and cooking utensils.
Malleability: Metals can be shaped and formed without breaking, allowing them to be used in various manufacturing processes.
Ductility: Metals can be drawn into wires, which is essential for making electrical cables and jewelry.
Strength: Metals are generally strong and durable, making them suitable for structural applications.
Luster: Metals have a characteristic shine or luster, which makes them visually appealing and useful in decorative applications.
Uses of Metals
Metals are used in a wide range of applications, including:
