The Advantages and Disadvantages of ASTM B124 C14200 Copper Material Properties, C14200 Properties


  • Excellent Electrical Conductivity: Copper here means C14200, which stands out for its electrical conduction capacity. Therefore, this is a preferred one for all applications with fast electrical transmissions.

  • Soft Material: This specific feature of the material can be taken advantage of precisely during manufacturing processes since it can be easily molded and molded, and keeps strength.

  • High Thermal Conductivity: C14200 is outstanding in reaching the right thermal conductivity level for example, heat exchangers, radiators, and incarnations applied for heat transport.

  • Good Corrosion Resistance: Regarding this material corrosion resistance is not as good yet, C14200 has enough anti-degradation properties to fight against several environmental ones.

  • Susceptibility to Oxidation: Because of its being of very higher grade, C14200 is, therefore, more oxidation-affected when in contact with air or moisture compared to other alloys.


  • Costlier Option: Because of the exclusive purity of oxygen free copper (OFC), with an example being C14200, and highly specialized manufacturing procedure, OFC is more expensive than standard copper alloys.

  • Limited Mechanical Strength: Besides its low hardness, C14200 shows some mechanical strength shortcomings when it comes to applications where high wear resistance is critical.

  • Unsuitable for High-Stress Environments: This negative impedes the application of C14200 as in the case of large structural components which are subjected to severe load bearing stresses.

  • Limited Work Hardening Ability: C14200 copper does not have any work hardening characteristic, which means it does not gain in improved hardness or toughness when exposed to plastic deformation by bending or hammering.

  • Susceptibility to Stress Corrosion Cracking: Whereas C14200 shows high corrosion resistance, it still possesses the limitation of stress corrosion cracking in the severe conditions.
