The Advantages and Disadvantages of ASTM B124 C14700 Copper Material Properties, C14700 Properties

    Advantages:

  • Excellent Electrical Conductivity: C14700 copper displays an ultimate merit in electric power transmission and thus is liked by many in areas where swiftness counts in the system.

  • Soft Material: Providing such functions in addition to being able to work with absolute precision without compromising strength makes it a perfect material for various production processes.

  • High Thermal Conductivity: C14700, having comparatively high conductivity, is often used in heat exchangers and radiators as a medium of heat exchange and transportation.

  • Good Corrosion Resistance: Although not fully resistant to the extend environmental awareness for a long time, aluminum alloy composition of C14700 gives its enough resistance to the environment factors.

  • Susceptibility to Oxidation: Because of its intense oxidation reactivity of the C14700 alloy, the problem of oxidation triggered by air or moisture is quite serious compared to other alloys.

    Disadvantages:

  • Costlier Option: The copper without oxygen (OFC), such as C14700, costs differently not only because its pureness is at the highest level but also for the complicated process to manufacture it which is very difficult to match with the conventional copper alloys.

  • Limited Mechanical Strength: Displaying a possessing low hardness, C14700, however, is characterized by insignificant mechanical strength, especially in (places prone to) wear and friction.

  • Unsuitable for High-Stress Environments: The C14700's low tensile strength and substantial load-related performance limitation reduce this material's suitability for main structural elements.

  • Limited Work Hardening Ability: C14700 is unchanged when harden at room temperature, which will not be harded or toughened whatever deformation it has been thought of.

  • Susceptibility to Stress Corrosion Cracking: Contrary to acids, C14700 is acid-resistant but under excessive load, it causes stress corrosion cracking.
