which metal is an alloy of copper and tin

The metal alloy made from copper and tin is bronze.

Bronze is one of the oldest man‑made alloys and typically contains about 80–90% copper and 10–20% tin, though the exact composition can vary by use. It is valued for its hardness, corrosion resistance, and attractive brown‑gold color, and is widely used for statues, bells, bearings, and marine fittings.
