What is TP1/C12000 copper?
C12000 Copper Strip/Foil, also known as Phosphorized, Low Residual Phosphorus (DHP) Copper, is a deoxidized copper with a small amount of phosphorus, which improves its corrosion resistance and makes it suitable for welding and brazing applications. This alloy is known for its excellent formability, high thermal and electrical conductivity, and good corrosion resistance.

Key Distinctions from Other Common Coppers
vs. C11000 (ETP Copper - Electrolytic Tough Pitch):
C11000 contains oxygen (~0.04%). It is not recommended for welding or high-temperature reducing atmospheres (risk of hydrogen embrittlement). C12000 is preferred for welded applications.
vs. C12200 (Similar DHP Copper):
C12200 has a slightly higher phosphorus range. They are often considered interchangeable for many applications, but C12200 is more common for plumbing tube.
vs. C10100 / C10200 (Oxygen-Free Copper):
OF coppers have higher conductivity (101% IACS) and superior ductility. They are used for high-vacuum electronics and critical conductors. C12000 is more economical for general plumbing and heat exchangers.
