Bronze is an early alloy in the history of metal smelting and casting. It is an alloy made by adding tin or lead to pure copper (red copper), which has special importance and historical significance.
Bronze is the name given by modern people. In ancient times, bronze was yellow with a reddish tint, but when buried in soil, its color turned green and gray due to oxidation, and it was called bronze. Compared with pure copper (red copper), bronze has higher strength and lower melting point (25% tin smelting bronze will lower the melting point to 800 ℃. The melting point of pure copper (red copper) is 1083 ℃). Bronze has good castability, wear resistance, and stable chemical properties.
