C10100 copper tube is a high-purity oxygen-free expansion (Oxygen-Free Electronic Copper, OFE) copper alloy with extremely low oxygen content, usually less than 0.001%. This copper tube is widely used in electronics, electrical appliances, communication equipment and other fields due to its excellent electrical and thermal conductivity.
C10100 copper tube has good plasticity and machinability and can be processed through a variety of processes such as cold rolling, drawing, annealing, etc. In addition, it also has excellent corrosion resistance and mechanical properties, allowing it to maintain stable performance in a variety of environments.

Core ingredients

Copper (Cu): ≥99.99% (most standards), some standards are ≥99.97% (Cu+Ag) or >99.95%.

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.
