The Advantages and Disadvantages of UNS C61400 Copper Material Properties, C61400 Properties


  • Excellent corrosion resistance: C61400, UNS or aluminum bronze, combines foundry application properties with superior resistance to marine and industrial environments.

  • High strength: It offers a high tensile and yield strength - a quality that makes it perfect for heavy-duty sections that need to be dependable and long-lasting.

  • Good wear resistance: The alloy shows outstanding wear resistance, and it is selected for applications that experience both high friction and mechanical wear.

  • Good thermal conductivity: The UNS C61400 alloy has a good thermal conductivity, which enables heat transfer, e.g. heat exchangers and cooling systems.

  • Non-sparking: It produces no sparks so it may be used in explosive areas where explosive gases or dust are present.


  • Cost: Copper alloy C61400 than copper alloys or other materials may be more expensive, so this may put a limit on its affordability in some cases.

  • Machining difficulty: Unlike other copper alloys, it can be trickier to machine it hence the need for specialized tools and techniques.

  • Limited availability: Based on the region or supplier, the UNS C61400 might have limited availability, which can result in longer lead times or higher cost attrition.

  • Potential for stress corrosion cracking: Although it has a good overall corrosion resistance, it has a propensity to the stress corrosion cracking under the specific circumstances.

  • Weight: Many aluminum bronze alloys including UNS C61400 can have density more than some other materials which may increase the total weight of components.
