Understanding C86500 Manganese Bronze Bushings

What Exactly is Manganese Bronze?

Manganese bronze, a type of bronze enriched with manganese and other alloying elements, boasts superior physical properties. Known for its corrosion resistance, ductility, strength, and thermal and electrical conductivity, manganese bronze stands out for its heightened strength owing to its alloy composition.

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.
