C22000

The captivating golden hue of this metal explains why it’s known as “Jewellery Bronze.” This exquisite brass can be polished and coated with lacquer to showcase its natural color or serve as a foundation for gold plating. Its moderate strength, corrosion resistance, electrical conductivity, and capability to be deep-drawn make C226 an excellent material choice for many design engineers working on functional applications, such as hinges, doorknobs, and specific electrical connectors.
