There are many common materials used in household appliances for their specific properties. Metals like stainless steel and aluminum are used for their durability and resistance to corrosion. Different types of plastics are used for strength combined with flexibility and resistance to impacts or chemicals.
Glass and ceramics both offer high heat resistance. Rubber is popular for gaskets, hoses, and other areas where an air- and water-tight seal is needed. Composites, such as fiberglass, are chosen for their combination of strength and light weight.
