UNS C62300 Aluminium Bronze Chemical Composition & Properties, Grades, Tables and PDF Online

UNSC-62300 or an aluminum bronze, which gets its good corrosion resistance and the high strength from the virtue of its structure, is a copper alloy. Its chemistry is usually a mixture of Copper (Cu), Aluminium (Al), Iron (Fe), and Nickel (Ni). The composition characterized by copper of about 87-90%, and the quantity of aluminum in between of 9-11% and with the trace of iron and nickel, C62300 bronze alloys presents better mechanical properties compared with other bronze alloys. It more than meets the requirements of wear resistance that are suitable for underwater applications, aerospace and rotatory machinery, among other. The traditionally used grades of this furnace steel are C62300, C62300 H01, and C62300 H02. A simple tables containing its mechanical properties (trengtensil strength and hardness) are available online and these aid in designing and producing. The property details of this modular flat can also be as tables, charts and PDF documents which can be used as comprehensive references.
