Key Properties of CuAl11Ni, 2.0981:
Composition: Primarily composed of copper (Cu) with significant aluminum (Al) and nickel (Ni) content. The designation “11” typically suggests around 11% aluminum, with nickel usually being around 5-6%.
Hardness and Wear Resistance: The presence of aluminum and nickel enhances the hardness and durability of the bronze, making it resistant to wear and galling.
Corrosion Resistance: Aluminum bronzes like CuAl11Ni are highly resistant to corrosion, including seawater and many acidic environments, which makes them suitable for various industrial applications.
Machinability: While not as easy to machine as some other bronzes, CuAl11Ni can still be machined with the right tools and techniques.
Applications:
Worm gears in worm gear reducers due to their ability to withstand high loads and provide a smooth transmission of motion with minimal wear.
High-load bearings and bushings, where durability and resistance to deformation are critical.
Marine hardware, where corrosion resistance is particularly valuable.
