CZ115

CZ115 is classified as a duplex high tensile brass alloy that intentionally limits its aluminum content to improve its soldering and brazing characteristics. It is occasionally referred to as manganese bronze. CZ115 sets itself apart by incorporating additional elements such as iron, tin, and manganese, which contribute to enhancing the physical and mechanical properties of the alloy, making it suitable for various applications.
