C67300 Manganese Bronze Alloy
C67300 manganese bronze is a high-strength wrought alloy that resists corrosion well. It works best in high-load applications when you need excellent wear resistance.
Many industries use C67300, including industrial and marine. Common applications include:
- Manganese Bronze Bearings
- Manganese Bronze Bushings
- Manganese Bronze Cams
- Manganese Bronze Drive Shafts
- Manganese Bronze Fasteners
- Manganese Bronze Gears
- Manganese Bronze Idler Pins
- Manganese Bronze Lead Screw Nuts
- Manganese Bronze Piston Heads
- Manganese Bronze Propeller Shaft
- Manganese Bronze Seal Rings
- Manganese Bronze Wear Plates
Diversified Bronze has solid and cored manganese bronze bars in 144" lengths. Other lengths and non-standard sizes are available.
