C86300 Manganese Bronze Alloy

C86300 manganese bronze is a strong alloy able to withstand high wear, heavy loads, and slow speeds. It is a durable alloy that cannot be heat treated. Because of its longevity, you can find it used in architecture frequently.

C86300 is often used in construction, electrical, industrial, and marine applications. Some specific applications include:

  • Manganese Bronze Pins
  • Manganese Bronze Bushings
  • Manganese Bronze Forming Dies
  • Manganese Bronze Heavy-Load Bearings
  • Manganese Bronze Hydraulic Cylinder Components
  • Manganese Bronze Valve Stems
  • Manganese Bronze Wear Rings

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

Technical Details

C86300 is made up of 60-68% copper, 25% zinc, 3-7.5% aluminum, 2.5-5% manganese, and 2-4% iron. The best welding techniques include coated metal arc. We do not recommend soldering, brazing, carbon arc, oxyacetylene, and gas shielded welding.
