C91300 is a copper alloy primarily used for casting purposes. It belongs to the tin bronze family but with a
high copper content. Due to its composition, it offers good castability but has limitations in terms of
mechanical properties compared to other copper alloys.

Common Questions and Answers:
What are the typical applications of C91300?
C91300 is primarily used for casting applications where good castability is crucial, and mechanical strength
is not a primary concern. Some potential applications include:
Ornamental castings: Statues, plaques, and other decorative elements can be cast from
C91300 due to its good castability and machinability for finishing touches.
Low-stress components: Certain applications might require cast copper components that
don't experience high stress or wear. C91300 could be an option in such cases.
Important Note: Due to the limited information available on specific applications, it's
crucial to consult with a material engineer or foundry specialist to determine if C91300 is suitable for
your specific casting needs.
How does C91300 compare to other copper alloys?
C91300 differs from many other copper alloys in its focus on castability. Compared to bronzes with higher
tin content (e.g., C91700), C91300 offers better castability but lower strength and wear resistance.
Are there alternative copper alloys for casting?
Yes, several other copper alloys offer good castability. Depending on the specific requirements, some
options include:
Aluminum bronzes (e.g., C95200): Offer good castability along with better strength and wear resistance
compared to C91300.
Leaded bronzes (e.g., C92200): While not ideal due to environmental concerns, some leaded bronzes might
provide a balance between castability, strength, and wear resistance depending on the application (consult
regulations).
Important Note: Always consult with a material engineer or foundry specialist to identify
the most suitable copper alloy for your specific casting application considering factors like castability,
mechanical properties, and regulatory compliance.
