Bronze is an alloy made of 88 percent copper and 12 percent tin. Other metals, such as aluminum, zinc, lead and silicon, are added to it frequently. It is malleable, ductile, lustrous, hard, golden brown in color, and a good conductor of heat and electricity.
Bronze is brittle and breaks easily. It has a low melting point and does not corrode easily. Bronze is generally nonmagnetic, but if iron and nickel are added, it shows magnetic properties. It is also lighter than steel.
An entire period in ancient history is devoted to the Bronze Age. This was the period when bronze was used extensively, and harder metals, such as iron, were yet to be discovered. Weapons, armor and even building materials are made of bronze.
