C22600

The alluring golden appearance of this metal explains why it’s known as “Jewellery Bronze.” This elegant brass can be polished and coated with lacquer to highlight its natural color or used as a foundation for gold plating. Its moderate strength, corrosion resistance, electrical conductivity, and capacity for deep drawing make C226 an excellent material choice for numerous design engineers working on practical applications, including hinges, doorknobs, and specific electrical connectors.
