Common Questions and Answers:
What are the typical applications of C91700?
C91700 is a versatile alloy used in various applications due to its well-rounded properties:
Gears: Its strength and wear resistance make it suitable for gears, particularly for
medium-load applications.
Bearings and bushings: C91700 can be used for bearings and bushings in applications with
moderate to high loads.
Wear plates and liners: Industrial machinery can benefit from C91700's wear resistance
for wear plates and liners.
Corrosion-resistant components: Due to its good corrosion resistance, C91700 can be found
in applications exposed to mild corrosive environments.
How does C91700 compare to other tin bronzes?
Unlike some high-lead tin bronzes (e.g., C93200. C93400), C91700 offers the advantage of being lead-free.
This makes it a safer and more environmentally friendly option. However, its machinability might be slightly
lower compared to leaded alternatives.
What are some limitations of C91700?
While C91700 offers many advantages, there are a few limitations to consider:
Cost: Compared to leaded bronzes, C91700 can be slightly more expensive.
Welding: Welding C91700 requires specific techniques to prevent cracking. Consulting a
welding professional is recommended.
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, wear resistance,
corrosion resistance, machinability, and cost.
