Metals and their alloys share many useful properties: they are good conductors of heat and electricity, can be cast, and are often lustrous. Throughout history, they have been widely used for functional and decorative objects, such as tools, weapons, jewellery, sculptures, coins, and medals. Metals are susceptible to corrosion, primarily from water and high humidity, but also from pollutants and other contaminants. Metal objects need proper care to prevent or minimize damage by corrosion.
