概述
General Description C12200， Phosphorus deoxidised copper， has been made weldable and brazeable by deoxidising with phosphorus. It is widely used as flat products and tubing， especially where it is to be welded or brazed. Phosphorus significantly reduces the conductivity， which may go as low as 70% IACS， but also raises the softening temperature when work hardened and promotes fine grain size.
C12200 has almost exactly the same mechanical properties as the high purity copper alloys such as C11000. It has excellent deep drawing characteristics and resistance to pitting corrosion when exposed to severe weather and water environments.

"(《世界人权宣言》) characteristics of Astm B111 C12200 Copper Tube
C12200 has similar corrosion resistance to C11000. It gives excellent resistance to weathering and very good resistance to many chemicals. It is often used specifically for corrosion resistance. It is suitable for use with most waters， and can be used underground because it resists soil corrosion. It resists non-oxidising mineral and organic acids， caustic solutions and saline solutions.
