The Advantages and Disadvantages of UNS C72150 Copper Material Properties, C72150 Properties


  • High Electrical Conductivity: C72150 copper has unique electrical conductivity which makes it perfect for electric conductors and wires.

  • Good Thermal Conductivity: In addition to it, the material also has high thermal conductivity, which enables heat removal or addition in elements like heat exchangers and cooling systems.

  • Corrosion Resistance: Copper under these conditions features outstanding corrosion resistance and is able to deal with such acidic as well as alkaline environments rather efficiently.

  • Machinability: This copper alloy, which is relatively easy to machine, makes the shaping and production of components with high precision possible.

  • Antimicrobial Properties: Copper in UNS C72150 is naturally antimicrobial. Therefore, the alloy is ideal for use in areas where hygiene matters the most, like the health care setting.


  • Cost: Copper, UNS C72150 in particular, may be costlier than metals like aluminum and steel for a given project, and this will affect the overall cost of the project.

  • Softness: Copper as compared to other metals is relatively soft, so it becomes more prone to deterioration and damage in certain conditions.

  • Weight: Copper is considerably denser than most other common metals, leaving this material with much higher weight for the components made out of it.

  • Oxidation: Copper is subject to oxidation which occurs only gradually, leading to a patina or tarnish of the surface. This could compromise its visual appearance within aesthetic applications.

  • Limited Strength: Although UNS C72150 copper possesses good mechanical properties, it might not be the strongest material and this is against its use in critical applications.
