The chemical composition of C10100 oxygen-free copper varies slightly in different standards:
Core ingredients
Copper (Cu): ≥99.99% (most standards), some standards are ≥99.97% (Cu+Ag) or >99.95%.
Oxygen (O): usually ≤0.001% (10ppm), but some standards are relaxed to ≤0.03% or ≤0.002%.
Impurity elements (maximum content)
Lead (Pb): ≤0.001% (common), occasionally ≤0.003%.
Sulfur (S): ≤0.0018% or ≤0.004%.
Phosphorus (P): ≤0.0003% or ≤0.002%.
Zinc (Zn): ≤0.0001% or ≤0.003%.
Other elements (such as Ca, Hg, Se, Te, Bi, As, etc.): all ≤0.0001%~0.002%.
C10100 is a high-purity oxygen-free copper (OFHC) whose mechanical properties vary significantly depending on the material state (such as annealing, cold working, etc.).
1. Tensile strength and yield strength
Annealed state (O state): tensile strength ranges from 200-235 MPa, and yield strength ≥80 MPa.
Cold working state: With the increase of cold working degree, the strength increases significantly:
1/2 hard state (1/2H): tensile strength ≥250 MPa, yield strength ≥350 MPa.
Full hard state (H): tensile strength can reach 300-455 MPa, and yield strength can reach up to 400 MPa.
Extreme cold working (such as EH state): tensile strength can be further increased to 550 MPa (other alloy states may refer to similar trends).
2. Elongation
Annealed state: the elongation is the highest, up to 35%-55%.
After cold working: the elongation drops significantly, such as ≥15% in 1/2H state and ≥2% in full hard state (H). Some data mention that the minimum elongation is ≥8%, which may correspond to a medium degree of cold working.
3. Hardness
Vickers hardness (HV): annealed state is about 75-90 HV, full hard state (H) can reach 90-120 HV.
Rockwell hardness: Rockwell F hardness is 40-100, Rockwell 30T hardness is 27-70.
4. Elasticity and shear properties
Elastic modulus: tensile modulus is 115 GPa, shear modulus is 44 GPa.
Poisson's ratio: 0.31-0.34.
5. Other mechanical properties
Shear strength: 150-240 MPa.
Fatigue strength and impact toughness: After cold hardening, the impact strength is improved, but the specific values need to refer to experimental data.
Creep resistance: High-purity oxygen-free copper shows good creep resistance.
6. Effect of state on performance
Annealing treatment (500-700°C): restore ductility and reduce strength.
Cold working (such as rolling, drawing): significantly improve strength, but sacrifice ductility.
Recrystallization temperature: The recrystallization starting temperature after cold hardening is 200-300°C.
Processing performance:
Supports rolling, drawing, forging, deep drawing and complex forming (such as waveguides, cavity resonators).
Good weldability, can use a variety of welding techniques, and no risk of hydrogen embrittlement
C10100 copper plate production process and product advantages:
1. Production process
Diversity of processing methods
C10100 copper alloy can be processed by a variety of processes, including rolling (hot rolling/cold rolling), drawing, die casting and forging. Its cold and hot processing properties are excellent, and its forgeability is good, which is suitable for forming complex shapes.
Key steps in the production process
The typical process flow includes: milling → heating → hot rolling → straightening → cold rolling → annealing → pickling → finishing rolling → finishing → inspection and packaging. The annealing process can adjust the hardness of the material, while special processes such as explosive welding can enhance its hardened state (such as H02 semi-hard state).
High purity control
The oxygen content is strictly controlled during the production process (≤5ppm), and the purity is ensured to be ≥99.99% through oxygen-free smelting technology to avoid the influence of impurities on conductivity.
2. Product advantages
Excellent electrical and thermal conductivity
C10100 has a conductivity of up to 101% IACS (International Annealed Copper Standard) and a thermal conductivity of 398 W/m·K, providing efficient energy transmission for electronic components, radiators and high-power devices.
Excellent processing characteristics
High ductility and plasticity: can be easily processed into complex shapes such as plates, bars, and tubes.
Good weldability: supports a variety of welding technologies and is easy to combine with other materials.
Adaptability to hot and cold processing: no need to affect performance due to processing steps, suitable for precision manufacturing.
Corrosion resistance and stability
The high purity gives it long-term stability in marine environments, high temperatures or chemical corrosion scenarios, reducing the risk of oxidation and degradation.
Wide range of applications
Electronics/semiconductors: used for heat sinks, AMB/DBC ceramic substrates, and chip heat dissipation covers to ensure efficient thermal management.
New energy: photovoltaic cell modules, electric vehicle connectors, and IGBT terminals to reduce resistance and improve efficiency.
Medical: manufacturing radiation therapy tools, high purity to reduce signal interference, and polished surface for easy disinfection.
Aerospace/shipbuilding: corrosion resistance is suitable for manufacturing ship equipment and aerospace components.
Industry recognition and standard compliance
Complies with international standards such as ASTM and AMS (such as ASTM-B-48, AMS 4700), and through strict quality control to ensure product consistency. The mature process of leading domestic companies (such as Xinke New Materials) further guarantees product reliability.
