C12200 Copper Sheet is a phosphorus-deoxidized copper material known for its excellent corrosion resistance, good electrical conductivity, and reliable fabrication performance. It provides dependable long-term performance in demanding industrial environments while maintaining excellent forming and joining characteristics.
Widely used in industrial equipment, engineering components, heat transfer systems, and applications requiring durability, corrosion resistance, and service reliability.
C12200 copper sheet (UNS C12200 copper plate, DHP high-phosphorus deoxidized copper panel, Cu-DHP bright annealed copper sheet metal, CW024A heavy plate, and architecturally polished copper sheet) is produced through advanced continuous casting, hot breakdown rolling, precision cold finishing, and bright protective atmosphere annealing. Engineered for HVAC refrigeration headers, solar collector heat absorption panels, architectural standing-seam roofing, underground earthing plates, chemical vessels, and heavy electrical bus bars, C12200 copper sheet offers superior ductility, excellent cold formability, 100% immunity to hydrogen embrittlement during high-temperature brazing, and exceptional long-term atmospheric corrosion resistance.
At XQJ Metal, we operate wide-width heavy plate rolling mills, precision hydraulic shearing lines, laser cutting systems, and bell-type bright hydrogen annealing furnaces to manufacture premium C12200 copper sheet and plate products conforming strictly to global engineering standards, including ASTM B152 (standard specification for copper sheet, strip, plate, and rolled bar), ASTM B370 (architectural copper sheet), EN 1652 (Cu-DHP / CW024A), JIS H3100 (C1220), and GB/T 2059 (TP2) specifications. We offer complete thickness options from 0.5mm to 50mm (0.020 inch to 2.0 inches), standard sheet dimensions of 1000x2000mm, 1220x2440mm (4×8 ft), and 1250x3000mm, as well as custom cut-to-size plates and custom tempers ranging from dead soft annealed to spring hard.
| Temper Designation | Standard Code & State | Thickness Range (mm / inch) | Tensile Strength (MPa) | Elongation (% in 50mm) | Primary Engineering Applications |

Q1: What is the primary difference between C12200 and C11000 copper sheet for roofing and HVAC?
A: C12200 is phosphorus deoxidized (Cu-DHP), making it completely immune to hydrogen embrittlement during high-temperature brazing and torch welding. While C11000 offers slightly higher electrical conductivity (100% IACS vs 85% IACS), C12200 is preferred for HVAC fabrication and architectural welding due to its superior joining characteristics.
Q2: Can XQJ Metal supply custom-sized C12200 copper plates with protective film on both sides?
A: Yes, we offer precision waterjet and laser cutting services to supply C12200 copper plates cut to your exact CAD dimensions, protected with heavy-duty 80-micron PE film on both sides to prevent scratching during handling and installation.
