C12000 Copper Strip is a phosphorus-deoxidized copper material offering good electrical 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 systems, industrial components, fabricated parts, and engineering applications requiring dependable processing performance and long-term service reliability.
C12200 copper strip (UNS C12200 DHP phosphorus-deoxidized copper strip, foil, and coil) is continuous-cast, cold-rolled, and bright-annealed to deliver exceptional thermal conductivity, superior deep-drawing ductility, clean surface finish, and 100% immunity to hydrogen embrittlement during high-temperature flame brazing and welding. Engineered specifically for HVAC heat exchanger fins, electrical transformer shielding, solar thermal absorbers, and precision progressive die stamping, high-purity C12200 copper strip guarantees tight thickness tolerances and reliable joint integrity under automated processing.
At XQJ Metal, we operate advanced four-high cold rolling mills, continuous atmosphere bright annealing furnaces, precision CNC coil slitting lines, and automated tension levelers to manufacture world-class C12200 copper strip products conforming strictly to global engineering standards, including ASTM B152 (copper sheet, strip, plate), ASTM B888, EN 1652, and JIS H3100 specifications. We supply full thickness ranges from 0.05mm to 3.0mm and coil slitting widths from 10mm to 600mm, available in soft annealed (O60), quarter-hard (H01), half-hard (H02), full-hard (H04), and extra-spring tempers.

Selecting between phosphorus-deoxidized C12200 copper strip and tough pitch copper (C11000 ETP strip) depends on flame welding requirements, deep-drawing formability, and operating temperature environment:
Transformer manufacturers, radiator fabricators, and machine shops rely on our C12200 copper strip coils for uninterrupted high-speed line feeding:
Our high-performance C12200 copper strip products are widely specified across multiple global manufacturing sectors:
To guarantee zero surface defects and 100% metallurgical consistency, XQJ Metal enforces strict Quality Assurance protocols on every C12200 copper strip batch:
Q1: Why is C12200 Copper Strip preferred over C11000 for flame-brazed heat exchangers?
A: C12200 Copper Strip is phosphorus-deoxidized (0.015%–0.040% P), completely eliminating hydrogen embrittlement micro-cracking during gas torch brazing, whereas C11000 ETP copper is vulnerable to cracking under high brazing temperatures.
Q2: What are the tightest thickness and slitting width tolerances XQJ Metal can achieve for C12200 copper strip?
A: We supply C12200 copper strip down to 0.05mm foil thickness with thickness tolerances within ±0.003mm and narrow slit widths down to 10mm with ±0.05mm width precision.
