TP1/C12000 copper Features
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.

FAQ
Q: What is the main difference between TP1 and TP2?
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.
Q: Is TP1 suitable for drinking water pipelines?
A: It must comply with GB/T 18033-2017 standards and pass migration testing for lead, arsenic, and other elements.
Q: How should TP1 be treated after cold working?
A: After cold work hardening, it should be annealed to restore ductility, with a recommended temperature of 500-600°C.
