Bronze 954
UNS C95400 is a cast aluminium bronze.
Identity / state reference
What distinguishes this material
It is not wrought C63000 and its casting/heat-treatment row must match the part.
- Designation in this reference
- UNS C95400
- Forms covered by the sources
- Casting
- States to distinguish or confirm
- As-cast or heat-treated condition must be identified
- 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.

Read the scope above: a source’s related product name is not a blanket interchangeability statement.
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 heat treatment produced this part and where is the acceptance test sampled?
- 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.
CDA UNS register — cast bronzes
Official entries for C93200 and C95400; cast alloy identity, not wrought-stock property equivalence.
CDA UNS register — cast bronzes ↗Wieland Concast — C95400
Manufacturer specific alloy page; form and condition must match the selected table. Published typical values and minimum limits are distinct.
Wieland Concast — C95400 ↗Wieland Concast — AMS 4590 C63020
Specific manufacturer AMS 4590-C63020 association, used to remove the mistaken C95400 equivalence. No cross-standard substitution granted.
Wieland Concast — AMS 4590 C63020 ↗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
- Remove the legacy AMS 4590 common-name mapping. The reviewed Concast catalogue associates AMS 4590 with C63020, not cast C95400.
- Remove universal 760 MPa/170 HB values and avoid equating all aluminium bronzes.
- Remove the untraceable generic machining recommendation (60 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.
