The Advantages and Disadvantages of ASTM B224 C10300 Copper Material Properties, C10300 Properties


  • Excellent Electrical Conductivity: The ASTM C10300 has high electrical conductivity of above 99%, thus making it the best choice for the applications where the current should flow efficiently such as electrical connectors, conductors and other electrical components.
  • High Thermal Conductivity: This material is characterized by its excellent thermogravimetricity feature which enables quick heat transfer hence, it is good for HVAC heat exchangers, refrigeration units and industrial processes.
  • Good Corrosion Resistance: C10300 has a smooth, non-scaling, forming bending, adhesive oxide layer that forms at the high temperatures the material is exposed to, and thus it is choice for plumbing systems like pipes, fittings, valves, and connectors.
  • Ductility and Formability: It has a high ductility which facilitates it to transform into different shapes during manufacturing processes.
  • Resistance to Hydrogen Embrittlement: C10300 displays a high degree of reliability under conditions of high hydrogen pressure exposure as well.


  • High Cost: Oxygen free copper, which is considered high-purity copper due to the lack of oxygen, is much more expensive compared to ordinary copper alloys as a result of the fabrication process and quality control.
  • Limited Availability: Copper alloys C10300 may be made difficult to access since it requires a special formulation.
  • Limited Strength: In the case of wrought C10300, it is an excellent conductor of electricity but it is also quite soft and does not have the required strength. In structural applications, we need to add further reinforcement.
  • Not Ideal for High-Temperature Applications: The C10300's melting point is so low that it would not be suitable for applications with elevated temperatures.
  • Susceptibility to Stress Corrosion Cracking: C10300 is likely to have cracks under some load conditions and thus it is important to take care of design aspects during its manufacturing.
