C12000 Copper Sheet is a phosphorus-deoxidized copper material offering good thermal conductivity, corrosion resistance, and enhanced welding and brazing performance. It provides reliable fabrication characteristics for industrial applications requiring durable and efficient copper components.
Widely used in heat transfer equipment, fabricated parts, industrial components, and engineering applications requiring dependable joining performance and long-term service reliability.
C12000 copper sheet (also known as DHP copper sheet, Phosphorus-Deoxidized C12000 plate, or CDA 120 copper strip) is a specialized high-purity copper alloy engineered for outstanding weldability, excellent brazing performance, and superior corrosion resistance. Containing a minimum copper purity of 99.90% with controlled residual phosphorus (0.015%–0.040%), C12000 copper sheet completely eliminates the risk of hydrogen embrittlement during high-temperature welding or brazing operations.
At XQJ Metal, we manufacture and supply premium C12000 copper sheets, plates, and coils across various tempers and custom dimensions. Produced in full compliance with ASTM B152, ASTM B272, and EN 1652 standards, our DHP copper sheets undergo precision rolling and bright annealing to ensure clean surface finishes, tight thickness tolerances, and excellent formability.

Q1: What is the main difference between C12000 and C11000 copper sheets?
A: C12000 is Phosphorus-Deoxidized (DHP) copper containing residual phosphorus, which prevents hydrogen embrittlement during high-temperature welding or brazing. C11000 is Electrolytic Tough Pitch (ETP) copper with higher electrical conductivity (100% IACS), ideal for electrical busbars, but susceptible to embrittlement when heated in hydrogen environments.
Q2: Can C12000 copper sheets be cold bent and stamped easily?
A: Yes, in Soft Annealed (O60) or Half Hard (H02) tempers, C12000 copper sheet exhibits superior ductility, making it easy to bend, stamp, and deep draw without cracking.
Q3: What is your Minimum Order Quantity (MOQ) for custom sheared C12000 sheets?
A: Our standard MOQ for custom cut-to-size C12000 sheets is 300 kg. Standard warehouse sizes can be shipped in smaller trial batch quantities immediately.
