Alloy is made of copper and tin and is yellow or brown in colour. It is harder than pure copper, more suitable for casting, and also resists corrosion. Bronze may contain as much as 25% tin, together with small amounts of other metals, mainly lead.

Bronze is one of the first metallic alloys known and was used widely by early peoples during the period of history known as the Bronze Age. Most Mediterranean civilizations were using Bronze for tools and weapons by 2500 B.C., replacing the previous 'copper only' period, which lasted approximately 1,000 years.

By 1500 BC bronze cutting implements were being used from the British Isles to China.

Charlemagne owned a water clock that marked hours by dropping bronze balls into a bowl as mechanical knights emerged from little doors.

Gold, silver and bronze medals were awarded for the first time at the 1904 Olympics.
