C61300 is an aluminum bronze copper alloy primarily composed of copper (88.5–91.5%), aluminum (6–7.5%), iron (2–3%), and tin (0.2–0.5%), with trace elements such as manganese, silicon, and nickel . This alloy exhibits exceptional mechanical properties, including a tensile strength of ~540 MPa (78,300 psi), yield strength of ~240 MPa (34,800 psi), elongation of 35%, and fatigue strength of ~180 MPa (26,100 psi), making it suitable for high-stress applications like bearings, gears, and marine components . Its corrosion resistance in marine, chemical, and high-temperature environments further enhances its utility in shipbuilding, aerospace, and heat exchangers
