C12200 copper sheet, also known as C122 DHP (Deoxidized High Phosphorus) copper, is used in plumbing systems, heat exchangers, HVAC equipment, and industrial fabrication. Its phosphorus-deoxidized composition provides good weldability and brazing performance while reducing the risk of hydrogen embrittlement during high-temperature processing.
The material offers corrosion resistance in many water-handling environments and can be bent, stamped, or deep-drawn depending on the selected temper. Its thermal conductivity makes it suitable for condenser components, fabricated water tanks, and other heat transfer equipment requiring formed copper parts.
Sky Steel Group offers C12200 copper sheets in various thicknesses, widths, lengths, and tempers, with custom cutting for specific manufacturing needs. C12200 copper sheet is covered by ASTM B152/B152M and corresponds to the European grade Cu-DHP (CW024A), specified under EN 1652. EN 10204 3.1 inspection certificates can be arranged subject to order requirements. Please specify dimensions, temper, and quantity when requesting a quotation.
Key Features of C12200 Copper Sheet

C12200 Copper Sheet Applications
HVAC & Refrigeration
C12200 copper sheets are used in HVAC and refrigeration equipment for fabricated condenser components, cooling assemblies, and connecting parts. Their brazing performance and resistance to hydrogen embrittlement during heating make them suitable for manufacturing joined copper components.
Metal Fabrication
C12200 copper sheets can be bent, stamped, and deep-drawn into custom parts, including brackets, housings, and formed panels. Annealed tempers are suitable for more demanding forming operations, while harder tempers may be selected when additional stiffness is required.
Heat Exchangers
C12200 copper sheets are used to manufacture heat transfer plates and formed components for industrial heat exchangers. Their thermal conductivity and corrosion resistance support applications involving water circulation, industrial heating, and temperature-control equipment.
Industrial Vessels
C12200 copper sheets can be fabricated into selected storage tanks, vessel components, and fluid-handling equipment. Their formability and brazing characteristics support shaped and joined copper assemblies. Material selection depends on operating temperature, fluid compatibility, and applicable design requirements.
Frequently Asked Questions About C12200 Copper Sheet (C122 DHP Copper)
1. What is C12200 copper sheet?
C12200 is phosphorus-deoxidized copper with high residual phosphorus, commonly called DHP copper. It is used for formed and joined copper components where brazing performance and formability are required.
2. What is the difference between C12200 and C11000 copper?
C12200 is phosphorus-deoxidized DHP copper, while C11000 is oxygen-bearing ETP copper. C12200 is commonly selected for brazed and welded components. C11000 has higher electrical conductivity and is commonly used for busbars and electrical parts.
3. What are the main applications of C12200 copper sheet?
Common applications include fabricated HVAC and refrigeration parts, heat exchanger components, formed panels, and selected vessel or fluid-handling components. Suitability depends on the service conditions and design requirements.
4. Can C12200 copper sheet be bent, stamped, or welded?
Yes. C12200 can be bent, stamped, and drawn, and is suitable for soldering, brazing, and suitable welding processes. Annealed material is generally preferred for demanding forming operations. The joining method and temper should be selected for the part design.
