UNS C86300 Copper Alloy Chemical Composition Properties, Grades, Chart and Pdf

UNS C86300 is a high-grade copper alloy that is widely used for equipments typically due to its remarkable wear tolerance and good corrosion behavior in quite many surroundings. Comprised of Cu, Zn, and Sn, it provides outstanding properties that are known for higher load-bearing capability; such property makes it suitable for various heavy-duty applications such as gears, bushings, and bearings. As well, this would also be suitable for alloying with other metals like Sn or Pb that are also beneficially heat treatable. Composition of UNS C86300 is usually constituted by 88% of copper and 6% of zinc, 4% of tin which possesses very good machinability and weldability properties. Its levels and qualities in accordance with trade standards, for high degree of reliability and quality of performance. Manufacturers and engineers typically read and assimilate the specifics of its functioning from large format charts and PDF files to gain a deeper understanding of them.

  • High strength: The UNS C86300 copper alloy, also known as manganese bronze, has excellent mechanical strength, which is why it is used for heavy-duty applications such as gears, bearings, and valve components.

  • Good wear resistance: It has excellent wear resistance, especially under high loads and sliding conditions, thus, it is suitable for applications that involve friction and mechanical wear.

  • High impact resistance: UNS C86300 has high impact resistance, thus, it is very durable and reliable in applications that are subjected to sudden shocks and vibrations.

  • Excellent machinability: The alloy is easily machinable, so it is possible to have a smooth production process and thus, the manufacturing of the complex components is cost-effective.

  • Corrosion resistance: Although it is not as corrosion-resistant as some other copper alloys, UNS C86300 still provides a good corrosion resistance in many environments, hence, increasing its durability and reliability.

    Disadvantages:

  • Cost: UNS C86300 copper alloy can be more expensive than the standard brass alloys or the other materials, which can be the reason why it is not affordable for certain applications.

  • Limited availability: The region or the supplier may limit the availability of UNS C86300, thus, the lead times or the procurement costs may increase.

  • Potential for galling: In some situations, UNS C86300 may be susceptible to galling which is a kind of adhesive wear that happens during the sliding contact, thus, lubrication and surface treatments are needed.

  • Casting limitations: The alloy may have the restrictions in the casting procedures because of its composition and mechanical properties, thus specialized casting techniques are needed for the best results.

  • Surface tarnishing: Although it has reasonable corrosion resistance, UNS C86300 may tarnish over time, especially in outdoor environments with exposure to pollutants, hence, periodic maintenance is needed to keep its appearance.
