C12200 Copper Strip 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 components, engineering equipment, precision fabricated parts, and applications requiring durability, corrosion resistance, and service reliability.
C12200 copper strip (UNS C12200 copper alloy strip, DHP high-phosphorus deoxidized copper tape, Cu-DHP bright annealed copper ribbon, CW024A slit strip coil, and fine gauge transformer copper foil) is manufactured through continuous casting, precision cold tandem rolling, and bright protective atmosphere annealing to deliver outstanding electrical and thermal conductivity, excellent deep drawing capability, superior brazing weldability, and 100% resistance to high-temperature hydrogen embrittlement. Engineered for electrical transformer foil windings, coaxial cable shielding wrap, HVAC heat exchanger fins, automotive radiator tanks, and electronic lead frames, C12200 copper strip provides uniform thickness tolerances and smooth burr-free slit edges.
At XQJ Metal, we operate ultra-precision multi-roll cold rolling mills, automated high-speed precision gang slitting lines, optical edge profilers, and bell-type bright hydrogen annealing furnaces to produce premium C12200 copper strip products conforming strictly to global engineering standards, including ASTM B152 (standard specification for copper sheet, strip, plate, and rolled bar), ASTM B888, EN 1652 (Cu-DHP / CW024A), JIS H3100 (C1220), and GB/T 2059 (TP2) specifications. We offer complete strip thicknesses from 0.05mm to 3.0mm (0.002 inch to 0.120 inch), slit widths from 5mm to 600mm (0.2 inch to 24 inches), inner coil diameters (ID 75mm, 100mm, 150mm, 300mm, 400mm, 508mm), and custom tempers ranging from dead soft annealed to spring hard.

Q1: What is the primary advantage of C12200 copper strip compared to C11000 for transformer windings?
A: C12200 is phosphorus deoxidized (Cu-DHP), making it completely immune to hydrogen embrittlement during high-temperature brazing of transformer leads. It also offers exceptional edge burr control and smooth ductility during tight automated foil winding.
Q2: Can XQJ Metal supply ultra-thin C12200 copper strip with rounded deburred edges for cable shielding?
A: Yes, we provide precision slitting down to 0.05mm thickness and 5mm width, with custom deburred or rounded safety edges to prevent cutting or tearing cable insulation jackets during high-speed wrapping.
