C22600

DESCRIPTION

The attractive golden hue of this metal makes it easy to understand how it received the name Jewellery Bronze. This beautiful brass can be buffed and lacquered to display its natural colour, or used as a base for gold plating. Its moderate strength, resistance to corrosion, electrical conductivity and ability to be deep drawn make C226 a great material option for many design engineers working on functional applications including hinges, doorknobs, and select electrical connectors.
