lead during machining.
Excellent machinability: Compared to some other copper alloys (e.g., leaded bronzes),
C87300 offers good machinability.
Good all-rounder: C87300 provides a balance of strength, wear resistance, and corrosion
resistance, making it suitable for various applications.
Are there any limitations to using C87300?
While C87300 offers many advantages, there are a few limitations to consider:
Cost: Compared to some copper alloys (e.g., brasses), C87300 can be slightly more
expensive.
Not ideal for high temperatures: The mechanical properties of C87300 can diminish at very
high temperatures.
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, regulatory compliance (lead content), cost, and operating temperature.
