C12200 Deoxidized High Phosphorus (DHP) copper closely matches the mechanical properties of high purity copper alloys like C11000, making it an excellent choice for various applications. Its outstanding deep drawing characteristics and resistance to pitting corrosion make it particularly well-suited for harsh weather and water environments. Offering similar corrosion resistance to C11000, C12200 excels in weathering and provides excellent protection against a wide range of chemicals, often selected specifically for its anti-corrosive properties. Its versatility allows for use with most waters and even underground, thanks to its resistance to soil corrosion. Additionally, C12200 proves its mettle against non-oxidizing mineral and organic acids, caustic solutions, and saline solutions.
C12200's deoxidized state, achieved through phosphorus addition, imparts weldability and brazeability, making it a popular choice for flat products and tubing, especially in welded or brazed applications. While phosphorus reduces conductivity, which may go as low as 70% IACS, it also elevates the softening temperature when work-hardened and promotes a fine grain size. These combined attributes position C12200 as a widely used copper alloy for numerous industries, offering reliable performance and resistance to corrosion in demanding environments.
