Why some metals are precious?

PRECIOUS METALS



Certain types of metals are precious or valuable. This may be because they are rare and difficult to obtain from their ores, so owning them has become a symbol of power and wealth. Some metals are prized for their beautiful colours and lustre or sheen. Some are valuable because they are easy to hammer or cast into detailed, intricate shapes such as thin wires or leaves.



Two of the main precious metals are gold and silver. People have fought wars and killed for them. These metals have become even more valuable recently because they are excellent carriers of electricity. They are used in switches, circuits and other devices in electrical equipment. Silver is also mixed with another metal, mercury, to make tooth fillings.
