Bronze 932
UNS C93200 is a cast high-leaded tin bronze.
Identity / state reference
What distinguishes this material
CDA separates casting routes and minimum from typical values; its bearing use does not prove a dry-running design.
- Designation in this reference
- UNS C93200
- Forms covered by the sources

- Temperature and exposure
- No general service-temperature limit or temperature-independent strength is established by this page. Check the temperature and duration for the specific source table and application.

Property evidence for a stated condition
No condition-specific numerical table is reproduced here
The linked sources establish the identity and the stated product/state scope. Obtain the row for your actual form, section, treatment and test conditions before adopting strength, hardness or a thermal limit.
Resolve these conditions next
- Which casting route and bearing lubrication/load specification apply?
- Obtain the full material certificate, governing specification/edition, product dimensions and test direction before adopting a property value.
For machining, take the exact grade, supplied condition and measured hardness where applicable into the tool maker’s application data. A generic material-family speed is not a substitute for an operation and tool-specific recommendation.
Sources and what they establish
Reviewed 23 October 2026. A source’s publication date and the review date are different. The scope below identifies the fields checked.
Copper Development Association — C93200
Specific alloy database entry; identity and listed form/temper distinctions. Direct fetch intermittently returns 403; indexed first-party text inspected on review date. No supplied-batch certification.
Copper Development Association — C93200 ↗Wieland Concast — C93200
Manufacturer specific alloy page; form and condition must match the selected table. Published typical values and minimum limits are distinct.
Wieland Concast — C93200 ↗Source identity, a named product example and a supplied-batch certificate are different evidence. Cross-standard similarity does not approve substitution.
Corrections from the previous article
- Correct the old lead composition 13–16%: the CDA C93200 entry specifies 6–8% Pb. Remove the unrelated CuSn7Pb15 correspondence; no cross-standard substitution is established.
- Do not call every C93200 item continuous-cast or inherently self-lubricating; remove unqualified 70 HRB.
- Remove the untraceable generic machining recommendation (120 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.
