How does adding tin atoms to copper change the structure of the metal?

Adding tin atoms to copper creates a solid solution or alloy known as bronzes, which alters the metal's structure by introducing interstitial or substitutional elements. This addition disrupts the regular lattice arrangement of copper atoms, enhancing properties such as strength, corrosion resistance, and ductility. The resulting microstructure can lead to improved mechanical performance and thermal stability compared to pure copper. Overall, tin atoms influence the crystallography and phase distribution within the copper matrix.
