Aluminium Bronze C63000
UNS C63000 is a wrought nickel-aluminium bronze.
Identity / state reference
What distinguishes this material
Wrought C63000 is distinct from cast aluminium bronzes such as C95400; product-standard and temper conditions matter.

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
- Is this wrought bar or a forging, and which heat treatment and product standard are required?
- 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 — C63000
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 — C63000 ↗Wieland Concast — C63000
Manufacturer specific alloy page; form and condition must match the selected table. Published typical values and minimum limits are distinct.
Wieland Concast — C63000 ↗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 unspecific 760 MPa/180 HB pair and implication that generic marine use proves suitability.
- Remove the untraceable generic machining recommendation (55 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.

Check the C95400 designation and product form separately; similar alloy-family wording does not establish an interchangeable product.
