Manganese bronze is a high-strength, copper-based alloy, often referred to as high-tensile brass or manganese aluminum bronze. It's characterized by its exceptional strength, excellent corrosion resistance, and good wear resistance. Key alloying elements include manganese, iron, aluminum, and sometimes lead, which contribute to its unique properties. 
Key Characteristics and Properties:
• High Strength: 

  Manganese bronze alloys are known for their high tensile strength, yield strength, and hardness, making them suitable for demanding applications. 
• Corrosion Resistance: 

  Like aluminum bronzes, they offer excellent resistance to corrosion, particularly in marine environments. 
• Wear Resistance: 

  Manganese bronze exhibits good wear resistance, making it suitable for components that experience friction and abrasion. 
• Machinability: 

  Many manganese bronze alloys are readily machinable, allowing for the creation of complex shapes and components. 
• Bearing Qualities: 

  Some manganese bronze alloys are specifically formulated for bearing applications, offering good load-bearing capacity and wear resistance. 
• Hot Working: 

  Certain grades can be hot-formed, making them suitable for applications involving welding, brazing, or soldering. 
• Color: 

  Manganese bronze, particularly UNS C86300, can have a distinct chocolate-brown color due to the manganese content. 
Common Uses:
• Marine Applications: Propellers, hardware, valve seats, and other components exposed to seawater. 
• Aerospace: Landing gear parts, strut bushings, and other high-strength components. 
• Oil and Gas: Components for pumps, valves, and other equipment in harsh environments. 
• General Engineering: Gears, bearings, bushings, lead screw nuts, and other heavily stressed parts. 
• Architecture: While not as common, manganese bronze can be used for its longevity and aesthetic appeal. 
Specific Alloys and Grades:
• C67500: Known for its excellent hot working characteristics. 
• C86300: A copper casting alloy with good corrosion resistance and used in architecture. 
• C86500: A high-tensile manganese bronze with high strength and hardness, suitable for gears, bearings, and other heavily stressed parts. 
• C66800: A naval brass with good strength, rigidity, and corrosion resistance. 
Important Considerations:
• Hard Shafts and Non-Abrasive Conditions: 

  Manganese bronze bearings require hard shafts and non-abrasive operating conditions to prevent wear and ensure optimal performance. 
• Residual Stresses: 

  When repairing or welding manganese bronze, it's crucial to avoid residual stresses that could lead to stress corrosion cracking. 
• Alloying Elements: 

  The specific composition of manganese bronze alloys can vary, influencing their properties and suitability for different applications. 

 

 

Manganese bronze is a high-strength copper-based alloy, also known as High Tensile Brass, characterized by high levels of zinc and added manganese, along with other elements like iron, aluminum, and sometimes lead, tin, nickel, or silicon. It offers high strength, hardness, corrosion resistance, and good machinability or hot-forming properties. Manganese bronze is used for heavy-duty applications such as gears, bearings, propellers, and pump components, especially in marine environments.
 
Key Characteristics
• Composition:

  Primarily copper and zinc, with manganese as a principal alloying element. Other elements like aluminum, iron, lead, and tin are often added to enhance properties. 
• High Strength and Hardness:

  Significantly stronger and harder than conventional brasses, capable of withstanding heavy loads and extreme conditions. 
• Corrosion Resistance:

  Excellent resistance to corrosion, particularly in marine and mildly acidic environments. 
• Anti-Seizing Properties:

  The presence of manganese and sometimes lead improves anti-seizing qualities, making it suitable for bearings and wear applications. 
• Machinability and Hot Forming:

  Offers good machinability and hot forming capabilities, which aids in the fabrication of complex components. 
• Good Bearing Properties:

  Performs well in high-speed, heavy-load bearing applications.
