The Advantages and Disadvantages of ASTM B111 C71500 Copper Material Properties, C71500 Properties

    Advantages:

  • Exceptional Electrical Conductivity: OFE Copper C71500 exhibit the highest electrical conductivity, absolutely essential for the electrical conductivity, which is the main value of the applications that need efficient electrical transmission.

  • Soft Material: This property is important in that it allows for easy forming, bending, and other manufacturing processes at which no physical weakness in the material is introduced.

  • Impressive Thermal Conductivity: C71500 is a renowned thermal conductivity material that qualifies it to be used in multiple functions which include heat transfer, radiators and heat exchangers.

  • Reasonable Corrosion Resistance: Though not as corrosive-proofing as some other copper alloys, C71500 still presents a reasoned resistance against environmental degradation.

  • Susceptibility to Oxidation: The OFHC C71500 copper is a higher purity material, which allows it to be more susceptible to oxidation when kept in air or moisture, so the frequent precautions needs to be taken during its storage.

    Disadvantages:

  • High Cost: Pure copper is contrary to other copper alloys such as C71500 so it is more expensive as a result of the purity and a complicated manufacture method.

  • Limited Strength: C71500 material has a relatively soft characteristic; hence, it could bring about issues in applications involving high levels of strengthening.

  • Not Ideal for High-Stress Environments: Its strength is reduced, and it more easily oxidizes than carbon steel do not make it the first choice for heavy-duty construction components.

  • Limited Work Hardening Ability: Copper alloy C71500 is incapable of work hardening hard as it tends to stay the same post plastic and deformation process.

  • Susceptibility to Stress Corrosion Cracking: Although a copper C71500 successfully resists general corrosion, it can still crack due SCC under certain circumstances.
