Microstructure of a CuAl7Si2 Aluminium Bronze consisting of a characteristic α-Cu matrix, annealing twins, and silicon-rich intermetallic phases.

These features contribute to the alloy’s excellent combination of strength, wear resistance, and corrosion resistance, making it ideal for demanding engineering applications.

Magnification: x500
Etchant: Ferric Chloride
