CDA 863 Manganese Bronze Bars & Tubing

C86300 Manganese Bronze Built Tough for Industrial Applications

C86300 manganese bronze components

Custom components made of CDA 863 manganese bronze.

American Iron & Alloys provides tough CDA 863 manganese bronze unprocessed bar stock or finished custom components for heavy load applications. C86300 performs best with reliable lubrication at low speeds. CDA 863 features high strength and corrosion resistance, better than general purpose bronzes for marine parts. The lead present in the chemical composition improves its machinability without having a major effect on its mechanical properties.

CDA 863 Bronze is Key for Many Industries

Non-heat treatable CDA 863 manganese bronze is used in the wood pulp industry, and is a key component in steel mill equipment and earth moving machinery. C86300 is good for coated metal arc welding, but not desirable for:

  • Soldering
  • Oxyacetylene welding
  • Gas shielded arc welding
  • Brazing
  • Carbon arc welding
