Different materials have different properties that make them suitable for different applications. Metals, wood, plastic, fabric, and ceramics are some of the most common materials. Properties like strength, weight, flexibility, conductivity, and resistance to heat and corrosion determine what material is best for a given product. For example, wood is often used for chairs due to its strength, toughness and appearance, while metals are suitable for pans and wires because of their heat conductivity and flexibility. Paper is well-suited for books because it is flexible, lightweight and can be printed on. Fabric provides insulation and flexibility for jackets.
