Deoxidized Copper Characteristics: Contains trace phosphorus (0.005-0.012%), excellent deoxidation ability, and significantly better welding performance compared to common copper.
High Conductivity/Thermal Conductivity: Conductivity ≥ 90% IACS, Thermal conductivity ≥ 350 W/(m·K), suitable for high-performance electrical and thermal conductivity applications.
Corrosion Resistance: Excellent resistance to high-temperature oxidation and steam corrosion, suitable for chemical pipelines, condensers, and other humid/high-temperature environments.
Workability:
Excellent cold working properties, can be made into thin-walled tubes or complex shapes.
For hot working, temperature control is required (annealing temperature: 500-700°C) to avoid grain coarsening.
Hydrogen Embrittlement Resistance: Phosphorus elements inhibit hydrogen penetration, reducing the risk of "hydrogen embrittlement" and enabling processing in reducing atmospheres.

Excellent Welding Performance: The phosphorus deoxidation process reduces oxidation risks, supporting high-precision processes such as flame welding and induction welding.
High Purity and Environmental Friendliness: Low impurity content, recyclable, and compliant with environmental requirements.
Balanced Performance: Combines excellent conductivity, thermal conductivity, and corrosion resistance, adaptable to multiple field requirements.
Refrigeration Industry: Air conditioning condenser tubes, refrigerator evaporators.
Chemical Equipment: Corrosion-resistant pipelines, reactor linings.
Electrical Electronics: Cable conductors, heat sink substrates.
Architectural Decoration: Art sculptures, weather-resistant roofing materials.
Welding Process: Prefer phosphorus-containing solder (e.g., BCuP series), preheat to 200-300°C before welding, and control sources of oxygen and hydrogen.
Annealing Control: Soft material annealing temperature ≤ 700°C, avoid repeated annealing to prevent grain coarsening.
Surface Treatment: After acid pickling, thoroughly rinse to prevent residual phosphides from causing corrosion.
A: TP1 has lower phosphorus content (0.005-0.012% vs. 0.015-0.040% in TP2), offering higher conductivity, but its welding performance is slightly inferior to TP2.
A: It must comply with GB/T 18033-2017 standards and pass migration testing for lead, arsenic, and other elements.
A: After cold work hardening, it should be annealed to restore ductility, with a recommended temperature of 500-600°C.
