The Advantages and Disadvantages of ASTM B124 C18200 Copper Material Properties, C18200 Properties

    Advantages:

  • Outstanding Electrical Conductivity: One of the significant qualities of C18200 copper is that it is the best for power transmission through the electric lines, especially for its high speed in critical systems.

  • Softness Advantage: The softness of this alloy makes it very useful for both fine tolerance work and stability, which makes it ideal for many production processes.

  • High Thermal Conductivity: C18200 stands out for its excellent conductivity quality which makes it a choice option in heat exchangers and radiators because of it's efficiency.

  • Decent Corrosion Resistance: Although its aluminum alloy constitution is not as invincible as tetracentane is, its acid resistance is satisfying.

  • Oxidation Vulnerability: While the high oxidative reactivity of C18200 alloy may reduce its corrosion resistance compared to other types of alloys, the two are closely related as the former can be oxidized easily under the effects of either air or moisture.

    Disadvantages:

  • Costlier Option: The electroless copper without oxygen (OFC), like C18200, might cost differently due to the straightforward fact that there is no other purest type of copper and also the lengthy and complicated process to manufacture such type of copper which might take some getting used to for the conventional copper alloys.

  • Limited Mechanical Strength: C18200, being soft, in terns of mechanical strength don't have any significant resistance in (such conditions where they are more likely to wear and tear) places prone to wear and friction.

  • Unsuitable for High-Stress Environments: Component with C18200 features low tensile strength and still need load-related performance make this material inappropriate for the main structural elements.

  • Limited Work Hardening Ability: C18200 is a ductulent steel whose hardness does not change when cooled at ambient temperature. Its toughness does not improve with any annealing process.

  • Susceptibility to Stress Corrosion Cracking: Indeed C18200 is resistant to acid but it has the tendency to initiate stress corrosion cracking when under excessive load.
