Technical Notes

Oxygen Content Impact:

Enhances recrystallization and grain refinement
Provides balanced strength-ductility relationship
Slightly reduces conductivity vs. oxygen-free copper
Risk of hydrogen embrittlement in reducing atmospheres

Temperature Limitations:

Softening begins around 200°C
Creep considerations above 150°C for long-term loading
Recrystallization temperature: 200-300°C depending on cold work

Design Considerations:

Coefficient of thermal expansion must be considered in multi-material assemblies
Galvanic compatibility with other metals in wet environments
Joint design critical for high-current applications
