C12200 is a grade of copper and is commonly referred to as "Phosphorized Copper" or "DHP Copper," which stands for "Deoxidized High Phosphorus." This copper alloy contains a higher phosphorus content compared to other copper grades, typically around 0.015% to 0.040% phosphorus, with the remaining composition being primarily copper.
C12200 copper offers several notable characteristics:
Excellent Corrosion Resistance: Like other copper alloys, C12200 exhibits good corrosion resistance, making it suitable for various environments.
Good Electrical Conductivity: It provides good electrical conductivity, although not as high as pure copper (C11000). This conductivity makes it suitable for electrical applications.
Improved Machinability: The added phosphorus enhances its machinability, making it easier to work with in machining and forming processes.
Enhanced Brazing and Soldering: C12200 copper is well-suited for brazing and soldering applications due to its composition.
High Ductility: It remains highly ductile, which means it can be readily formed into various shapes and configurations.
C12200 is used in a wide range of applications, including electrical connectors, plumbing components, heat exchangers, and various other parts that require good corrosion resistance, electrical conductivity, and ease of fabrication. The increased phosphorus content in C12200 enhances certain properties compared to pure copper while maintaining its suitability for many applications.
