C83800 copper wire is a tin-bronze alloy with a tin content of approximately 3%. It combines excellent mechanical properties with corrosion resistance. With a Brinell hardness of approximately 60 and a tensile strength exceeding 200 MPa, it is particularly suitable for manufacturing wear-resistant mechanical components such as bearings and gear bushings. It also offers long-term stable operation in humid or salty environments.
This copper wire is also characterized by its excellent electrical conductivity and processability, making it suitable for both electrical connectors and the formation of complex parts through hot and cold processing. Its dense surface oxide film further enhances its resistance to environmental corrosion, making it widely used in industrial applications such as shipbuilding components, chemical equipment, and steam systems.
