Aluminum bronzes and Nickel Aluminum Bronzes contain high amount fo Aluminum say between 3% and 12% which strengthens the alloy. They are best known for their high corrosion and oxidation resistance combined with exceptionally good mechanical properties. Aluminum bronze bearings are used in heavily loaded applications. Alloys such as C954 or C955 can be quenched and tempered to reach even higher strengths when necessary. Resistance to seawater corrosion is extremely high in nickel aluminum bronzes such as C955. Due to its resistance to corrosion, erosion, and cavitation, it is widely used for propellers and other marine hardware.
Typical uses:
- Electrical clamps
- Landing gear parts
- Pickling tank and mild alkali applications
- Marine engine and propellers
- Gears
- Terminals and connectors from Bronze
- Stripper nuts
- Slippers
- High temperature applications
- Mining machine parts
- Spur and low speed – heavily loaded worm gears
- Nuts
- Pumps
- Bushings
- Tank gun recoil mechanisms
- Valve guides and seats in aircraft engines
- Cable connectors
- Pole-line hardware
- Terminals
- Propeller hubs
- Blades and other parts including valves with sea water contact
