Aluminium Bronze Circles typically consist of copper (80–90%), aluminium (5–11%), and trace amounts of iron, nickel, or manganese. This alloy boasts remarkable mechanical strength, fatigue resistance, and corrosion resistance in seawater and harsh environments. The usual tensile strength falls between 450–850 MPa, with yield strength around 150–500 MPa, depending on the specific grade and heat treatment. These circles also show good ductility and hardness, making them perfect for high-performance applications like heavy load-bearing and anti-friction components
