CW721R equivalent to CZ114 is a standard high tensile brass stronger then conventional brass. It comes with added Aluminium which improves its mechanical properties as well as brighter finish. The addition of Tin and Manganese improves its resistance to corrosion in marine and mildy acidic environments, whereas the added Iron content acts as a grain refiner. CW721R offers a reasonable machinability but good hot forming capability which makes it suitable for Valves, Marine and Architectural components.
