C92300 is a copper alloy belonging to the leaded tin bronze family. It's known for its good combination
of strength, wear resistance, and machinability, making it suitable for various industrial applications,
particularly gears and bushings. However, similar to other leaded alloys, its use is becoming less common
due to environmental and health concerns.

Common Questions and Answers:
What are the main applications of C92300?
C92300 finds use in various industries due to its balanced properties:
Gears: Its strength and wear resistance make it suitable for gears, especially for
lower-load applications.
Bearings and bushings: C92300 can be used for bearings and bushings in applications with
moderate loads.
Wear plates and liners: Industrial machinery can benefit from C92300's wear resistance
for wear plates and liners.
What are the limitations of using C92300?
The main limitations of C92300 are:
Lead content: Lead is a health hazard during machining and limits applications in some
industries due to environmental regulations.
Fair corrosion resistance: C92300 is not ideal for environments with high corrosion
potential.
Are there lead-free alternatives to C92300?
Lead-free alternatives can be considered depending on the specific application requirements. Here are some
options:
C93700: A high-tin bronze with good machinability and wear resistance for bearings and
bushings, but no lead.
Aluminum bronzes (e.g., C95400): Offer good strength, wear resistance, and machinability
without lead.
Important Note: Regulations on lead usage can influence the availability of C92300. Lead
content should also be a factor when choosing a material. 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, and regulatory compliance.
