Frequently Asked Questions
Common questions about C95400 Aluminum Bronze specifications and applications.
C95400 Aluminum Bronze is commonly used for bearings and bushings, gears and worm wheels, valve components, pump parts, marine hardware, and pickling hooks. Its combination of high strength, excellent wear resistance, and corrosion resistance makes it ideal for heavy-duty industrial applications.
C95400 has a machinability rating of 60 (on a scale where free-cutting brass C36000 = 100). This indicates good machinability for an aluminum bronze, allowing for efficient machining operations with proper tooling and cutting parameters.
C95400 Aluminum Bronze has a tensile strength range of 75-90 ksi (517-621 MPa), depending on the casting method and heat treatment. This high strength is comparable to medium carbon steel, making it suitable for structural and load-bearing applications.
Yes, C95400 offers excellent corrosion resistance, particularly in seawater environments. It resists dezincification, stress corrosion cracking, and cavitation erosion, making it well-suited for marine hardware, ship building components, and covers for marine hardware.
Yes, C95400 can be heat treated to enhance its mechanical properties. Solution treatment at 1600-1675°F followed by water quenching, then tempering at 1150-1225°F, can increase tensile strength to 90-105 ksi and hardness to 190-195 Brinell.
