C91100 is a copper alloy belonging to the tin bronze family. However, compared to other copper alloys
previously discussed, information readily available online about C91100 is limited. Here's what we can
gather based on the limited sources found:
Possible Chemical Composition:
Primarily Copper (Cu): Likely high copper content with a significant amount.
Tin (Sn): Potentially between 4% and 8% based on the naming convention of similar tin bronzes.
Other elements (Fe, Zn, Pb): Trace amounts possible.
Potential Properties:
Likely good castability due to the copper content.
Possible good machinability depending on the specific composition (uncertain about lead content).
Moderate strength and wear resistance based on the tin content (specific values unknown).
Possible Applications (educated guesses based on similar alloys):
Bearings and bushings in low to moderate load applications.
Wear plates and liners in industrial machinery.
Decorative castings due to potential good castability (depending on the application).

Common Questions and Answers:
What are the specific properties of C91100?
Unfortunately, without consulting a material datasheet or contacting a copper alloy supplier, pinpointing
the exact properties of C91100 is difficult. The composition information found online is speculative based
on the naming convention of similar alloys.
What are the applications of C91100?
Similar to the properties, specific applications are uncertain. Based on the tin content, C91100 might be
suitable for bearings, bushings, and wear plates in low to moderate load applications. Decorative castings
could also be a possibility due to potential good castability. However, confirmation is needed from a
reliable source.
Are there alternative copper alloys with better information available?
Yes, several copper alloys with well-documented properties can be considered depending on your specific
needs:
C91300: Offers good castability for low-stress components.
C91700: High-tin bronze with excellent strength, wear resistance, and good corrosion
resistance (lead-free).
Leaded tin bronzes (e.g., C92200. C93200): While not ideal due to environmental concerns,
some leaded bronzes offer a balance between castability, strength, and wear resistance (consult
regulations).
Important Note: Always consult with a material engineer or supplier to identify the most
suitable copper alloy for your specific application considering factors like desired properties,
castability, and regulatory compliance. They can provide you with datasheets and recommendations based on
your needs.
