C12200 Copper Wire 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 flexibility and processing characteristics.
Widely used in industrial equipment, engineering components, electrical systems, and applications requiring durability, corrosion resistance, and service reliability.
C12200 copper wire (UNS C12200 copper alloy wire, DHP high-phosphorus deoxidized copper wire, Cu-DHP bright annealed copper wire, CW024A industrial wire, and fine gauge copper magnet wire) is produced through precision continuous casting, cold drawing, and bright hydrogen annealing to deliver exceptional electrical conductivity, high thermal efficiency, superior cold workability, and 100% resistance to hydrogen embrittlement. Engineered for HVAC refrigeration lines, electrical transformers, motor windings, welding filler rods, silver brazing alloys, and chemical processing equipment, C12200 copper wire provides dependable ductile performance and high corrosion resistance in demanding atmospheric and industrial environments.
At XQJ Metal, we operate advanced multi-wire drawing machines, continuous bright annealing furnaces, tension levelers, and automated precision spooling equipment to manufacture premium C12200 copper wire conforming strictly to global engineering standards, including ASTM B75 (seamless copper tube & wire stock), ASTM B152, ASTM B68, EN 12449 (Cu-DHP / CW024A), JIS H3300 (C1220), and GB/T 5231 (TP2) specifications. We offer complete wire diameter ranges from 0.1mm to 8.0mm (0.004 inch to 0.315 inch), custom spool sizes (DIN125, DIN200, DIN250, K355), coil bundles from 5kg to 500kg, and custom temper designations from dead soft annealed to full hard.
