loads.
Marine hardware: C95400 offers moderate corrosion resistance for some marine hardware
applications.
Architectural elements: Due to its castability and aesthetics, C95400 can be used for
decorative elements like railings and plaques.
How does C95400 compare to other copper alloys?
C95400 offers a good balance:
Versatility: Compared to some specialized copper alloys, C95400 offers a balance of
properties suitable for various applications.
Castability: It offers good castability for intricate shapes, making it suitable for
complex components.
Are there alternatives to C95400?
Depending on the specific needs, consider these alternatives:
High-strength aluminum bronzes: Offer superior strength but might be more expensive and
have lower castability.
Leaded brasses (e.g., C85700): Can provide good castability and machinability at a lower
cost, but with lower strength and environmental concerns due to lead.
Silicon bronzes (e.g., C65620): Offer good castability, corrosion resistance, and fair
strength, but might lack the same machinability.
Important Note: Always consult with a material engineer or supplier to identify the most
suitable copper alloy for your specific application considering factors like strength, castability,
corrosion resistance, machinability, lead content (regulations), and cost.
