C63200

Q: What is C63200 Nickel Aluminum Bronze used for?

C63200 Nickel Aluminum Bronze is commonly used for fasteners and bolting, marine pump bodies and valves, drive shafts for seawater service, and bearing cages and sleeves. It offers excellent corrosion resistance in marine environments combined with high strength.

Q: What is the machinability rating of C63200?

C63200 has a machinability rating of 30 (on a scale where free-cutting brass C36000 = 100). This indicates moderate machinability, requiring appropriate tooling and cutting parameters for optimal results.

Q: What is the tensile strength of C63200?

C63200 has a tensile strength range of 95–105 ksi. This high strength makes it ideal for demanding marine and industrial applications requiring superior mechanical properties.

Q: How does C63200 compare to C63000?

C63200 and C63000 are both nickel aluminum bronzes with similar corrosion resistance. C63200 has a higher iron content (4.0-4.3% vs 2.0-4.0%) and lower nickel content (1.2-2.0% vs 4.0-5.5%), offering excellent weldability and forgeability at a more economical cost point.

Q: What forms is C63200 available in?

C63200 is a wrought alloy available as forgings, plate, rod, bar, and shapes. It has excellent forgeability (rated 70) and is commonly used for forged components in marine applications.
