Common Questions and Answers:
What are the typical applications of C95800?
C95800 finds use in various industries due to its well-rounded properties:
Gears: High-strength gears, particularly for medium- to high-load applications, can be made
from C95800.
Bearings and bushings: In applications with demanding loads, C95800 is a suitable choice
for bearings and bushings.
Wear plates and liners: Industrial machinery can benefit from C95800's wear resistance
for wear plates and liners.
Marine applications: While not ideal for constantly submerged environments due to potential
for dezincification, C95800 can be used for some marine hardware due to its good corrosion resistance.
How does C95800 compare to other copper alloys?
C95800 offers several advantages:
Excellent combination of properties: It provides a balance of high strength, wear
resistance, and good corrosion resistance.
Good machinability: Compared to some other high-strength copper alloys, C95800 offers good
machinability.
Are there alternatives to C95800?
Depending on the specific application requirements, some alternative copper alloys can be considered:
Silicon bronzes (e.g., C65620): Offer good corrosion resistance but might have lower
strength.
High-tin bronzes (e.g., C93700): Excellent wear resistance but might be more expensive and
have lower strength compared to C95800.
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. Be aware of potential dezincification concerns in saltwater
environments.
