Manganese Bronze UNS-C86500

UNS C86500a

High-strength yellow brass–copper casting alloy UNS C86500 is a cast alloy consisting mainly if copper and zinc. UNS C86500 is preferred by architects for its color and longevity. The lead in the alloy gives it a golden color where as the manganese gives chocolate brown color.

UNS-C86500 Corrosion Resistant
C86500 is a high-strength and hardness copper-zinc alloy. It has low tensile strength but good corrosion resistance. Also known as C12A, this alloy does well under high speeds and loads. This alloy contains 58% copper and 38% zinc.
 Advantages

Manganese bronze is often specified over other bronzes for its exceptional longevity. It can withstand wear and corrosion better than most other bronzes thanks to its added manganese, and while not heat-treatable, it boasts an impressive strength profile. It is resistant to seawater corrosion (though less so than silicon bronzes), and is both hot forgeable and castable, if desired. Its main disadvantage is its price tag, as it is one of the more complex bronzes to fabricate. Also, it must be reliably lubricated to work optimally, as abrasive conditions will weaken the alloy’s integrity.

 

Conclusion

Manganese Bronze is a high-strength European bronze alloy that is meant to be used at high-speed loads. Alloys of manganese bronze possess perfect mechanical properties and good corrosive resistance. Nevertheless, they need a reliable lubricant. Such bronze alloys are high-workable. The following alloys relate to this group: C86100, C86200, C86300, C86400, C86700, C86500, C86800.
