UNS C86200, otherwise known as manganese bronze, is a well-recognized alloy which possesses remarkable mechanical characteristics and corrosion resistance. It average Chemical composition normally contains Copper (Cu), manganese (Mn), and zinc (Zn) among other elements. The grades of UNS C86200 class of alloy differ by their constituents, the major one determines the grade by manganese which, in turn, has an influence on the properties. This alloy is widely used in a marine environment owing to its capability to resist corrosion in salt water, in addition in applications that need great wear and high mechanical strength. The tables and charts presenting the composition and mechanical properties of different grades of metal are present in the technical documents which can be used for information needs for metal applications. The UNS C86200 Manganese Bronze comes in handy when it comes to the choice of material in different applications of the different industries.
UNS C86200, better known as manganese bronze, is another category of copper alloy, which has high strength, versatility and resistance to corrosion and wear. Made of copper (Cu), manganese (Mn) and small amounts of other elements, its chemical components usually includes copper (Cu) that ranges from 60 to 65%, manganese (Mn) approximately 2 to 5%, and zinc (Zn) which is 22 to 27%. Other trace elements, such as aluminum (Al) and iron (Fe), may be present in smaller amounts. Manganese bronze classing is based on its mechanical features enabling its use in different applications e.g. marine placements, valve stems, gears, and hydraulic bushings, among many others.
Elements | Cu | Zn | Al | Mn | Fe | Ni | Pb | Sn |

Max (%) | 68.0 | 26.0 | 7.5 | 5.0 | 4.0 | 1.0 | 0.2 | 0.2 |
Advantages:
High Strength: Mechanical strength of UNS C86200 is high and this allows it to be used in heavy industries involving gears and bushings.
Good Wear Resistance: This gives the alloy superior wear properties which are essential for components subjected to friction and mechanical stress.
Corrosion Resistance: It displays low corrosion resistance, especially for marine and industrial applications, making it perfect for marine hardware and pump parts.
Machinability:The machining of UNS C86200 is not that difficult, which can help get the necessary parts and components that are complex.
Dimensional Stability: The alloy presents excellent dimensional stability against thermal and loading variations guaranteeing optimal performance.
Disadvantages:
Cost: This composition, however, is more costly than usual copper alloys because of the price of these other elements and manganese.
Limited Weldability: Welding UNS C86200 is a difficult task and may require some special welding methods or expertise, which limits the use of this material in some industries.
Brittleness: Manganese is a factor that can sometimes increase brittleness and it is thus not appropriate in applications calling for high ductility and toughness.
Potential for De-zincification: The zinc component may corrode in some of the aggressive environments which can weaken the alloy with time. This phenomenon is however called de-zincification.
Availability of Shapes: The various shapes and forms that can be achieved may be more limited than those copper alloys that are more commonly used leading to challenges in finding the sourcing and manufacture.
