C10200 copper tube is a copper tube made of high-purity oxygen-free copper (Oxygen-Free Copper, OFC), which has excellent electrical and thermal conductivity, as well as good ductility and creep resistance. This copper tube is widely used in electrical equipment, electronic components, refrigeration systems, air-conditioning equipment, waveguides, etc. due to its high purity and no hydrogen embrittlement.

Oxygen (O) content: generally ≤0.003% (30 ppm), ≤0.001% (such as vacuum application scenarios).
Impurity restrictions:
Lead (Pb) ≤0.004%, iron (Fe) ≤0.004%, sulfur (S) ≤0.004%, zinc (Zn) ≤0.003%, others such as bismuth (Bi), antimony (Sb), arsenic (As), nickel (Ni), etc. are all subject to restrictions.
Mechanical properties vary significantly depending on the material state (annealed, hard, etc.):
Tensile strength:
Soft state (annealed): 215-275 MPa (≈31.8-40 ksi).
Hard state (cold worked): 261-441 MPa (≈38-64 ksi), up to 462 MPa (67 ksi).
Yield strength:
Soft state: 49-78 MPa (≈7-11 ksi).
Hard state: 290-400 MPa (≈42-58 ksi).
3. Elongation:
Soft state: 35-55% (excellent plasticity after annealing).
Hard state: 10-15% (plasticity decreases after cold working).
Hardness:
Brinell hardness (HB): 35-45 HB in soft state, 85-95 HB in hard state.
Rockwell hardness: HRB 40 (soft), HRB 57-100 (hard).
Other properties:
Density: 8.90-8.94 g/cm³.
Modulus of elasticity: 115-120 GPa.
Shear strength: 150-240 MPa.
Thermal and electrical properties
Thermal conductivity: 383-391 W/(m·K) (20℃), equivalent to 100% IACS conductivity.
Melting point: 1080-1083℃.
Thermal expansion coefficient: 17.0-17.7 µm/m·℃ (20-300℃).
Annealing temperature: 375-650℃, hot working temperature: 750-875℃.
