C86500 Manganese Bronze

Self-lubricating bronze bearings are engineered for applications where external lubrication is impractical. Solid lubricants are compressed and molded directly into the bearing to guarantee a maintenance-free product. No additional lubrication is necessary.

Understanding C86500 Manganese Bronze Bushings

What Exactly is Manganese Bronze?

CuZn35Al1 C86500 Manganese Bronze is a high-strength, corrosion-resistant copper alloy that is primarily composed of copper (typically around 65%) and manganese (around 15-25%). It is known for its excellent mechanical properties, such as high tensile strength and good ductility, which make it suitable for a wide range of applications where strength and durability are required.

Taxonomy within the Family of Bronze Alloys

Bronze is an alloy that is primarily composed of copper, and it can be further categorized based on the alloying elements it contains. C86500 Manganese Bronze belongs to the broader family of bronze alloys, which can be classified as follows:

  • Copper Alloys: These are alloys that are predominantly copper, with other elements added to enhance specific properties.
  • Copper-Nickel Alloys: These alloys contain nickel as the major alloying element, known for their resistance to corrosion and seawater.
  • Copper-Zinc Alloys (Brass): Brass is an alloy of copper and zinc, valued for its acoustic properties and ease of machinability.
  • Copper-Tin Alloys: Traditional bronzes with tin as the major alloying element, known for their casting properties and corrosion resistance.
  • Special Bronzes: These include alloys like C86500 Manganese Bronze, which have specific alloying elements that impart unique characteristics.

Comparison with Other Bronze Alloys (Aluminum Bronze, Silicon Bronze, etc.)

C86500 Manganese Bronze can be compared with other types of bronze alloys based on various properties:

Aluminum Bronze: These alloys are known for their excellent corrosion resistance, particularly in marine environments. They have high strength and good wear resistance but are generally more difficult to machine compared to C86500 Manganese Bronze.

Silicon Bronze: Silicon bronzes have good corrosion resistance and are known for their casting properties. They have a lower tensile strength compared to C86500 Manganese Bronze but offer better resistance to deformation under load.

Phosphor Bronze: These are typically high-strength alloys with good electrical conductivity. They are often used for springs and electrical contacts but do not offer the same level of corrosion resistance as C86500 Manganese Bronze.

C86500 Manganese Bronze: It stands out for its high strength and good ductility, making it ideal for applications requiring high mechanical properties. It also offers good corrosion resistance, though not as high as aluminum bronze in certain environments.

Each type of bronze alloy has its own set of advantages and is chosen based on the specific requirements of the application it is intended for. C86500 Manganese Bronze, with its unique combination of properties, finds use in various sectors, including marine, aerospace, and general engineering applications.

Production Process of Manganese Bronze

Derived from Muntz metal, a brass alloy, manganese bronzes undergo a manufacturing process involving the melting of copper followed by the addition of zinc and other alloying metals. The resultant molten manganese bronze is then cast into molds to solidify into ingots.

Distinction from Other Bronzes

Manganese bronze outperforms its counterparts in wear and corrosion resistance, courtesy of the manganese infusion. This characteristic makes it a preferred choice for applications demanding high fatigue strength and corrosion resistance, particularly in marine settings.

Composition and Characteristics

Manganese bronze primarily comprises copper and zinc, along with manganese, iron, aluminum, lead, and tin in varying proportions. Its mechanical properties, exemplified by its yield strength of 460 MPa and tensile strength of 820 MPa (for instance, UNS C86300), distinguish it from other bronze variants.
