C86400 Manganese Bronze Alloy

C86400 manganese bronze resists wear and has high corrosion resistance. Including lead increases the machinability of the alloy, which has a golden color. People often call C86400 architectural bronze because it is often used in architecture.

Typical industries that use C86400 include consumer, electrical, industrial, marine, and plumbing. Manufacturers use C86400 in roller bearing applications. Some typical applications include:

  • Manganese Bronze Bearings
  • Manganese Bronze Gears
  • Manganese Bronze Lever Arms
  • Manganese Bronze Short Circuit Strips
  • Manganese Bronze Struts
  • Manganese Bronze Valve Stems

Diversified Bronze has solid and cored bronze bars in 144" lengths. Other lengths and non-standard sizes are available.

Technical Details

C86400 is made up of 56-62% copper, 37-40% zinc, 0.5-1.5% lead, and less than 2% iron. The best welding techniques include brazing and soldering. We do not recommend other welding methods.
