C67410 Manganese Bronze Alloy

Much like other manganese bronze alloys, C67410 resists corrosion well. When used in bearings, C67410 can handle high speeds and heavy loads. By including manganese, iron, and aluminum, this alloy resists seizing.

C67410 has high strength for use in heavy-load applications. Some typical uses include:

  • Manganese Bronze Bushings
  • Manganese Bronze Cams
  • Manganese Bronze Connecting Rods
  • Manganese Bronze Cylinder Liners
  • Manganese Bronze Gears
  • Manganese Bronze Hydraulic Piston Shoes
  • Manganese Bronze Shafts
  • Manganese Bronze Valve Guides & Chain Guides
  • Manganese Bronze Wear Plates

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

Technical Details

C67410 is made up of 55.5-59% copper, 2% nickel, 1.3-2.3% aluminum, 1.0-2.4% manganese, and 1% iron. The best welding techniques include:

  • Brazing
  • Butt
  • Gas-Shielded Arc
  • Seam
  • Soldering
  • Spot
