Be specific about copper-nickel
Where a project uses copper-nickel, identify the full grade rather than a generic Cu-Ni label. Use the project’s exact material specification.
Different alloy families.
Distinct requirements.
Copper, brass, bronze and copper-nickel describe different material families. Identify the exact alloy designation and fitting requirements before requesting a quotation.
GRADE OVERVIEW
Start with the complete designation
The grade references below help structure an enquiry. They are not a statement of stock, equivalence or suitability for a particular service.
| Grade / detail | What to specify |
|---|---|
| Copper | Provide the exact material designation and product specification. |
| Brass | Name the requested alloy; the family name alone is insufficient. |
| Bronze | Specify the alloy designation and required supply condition. |
| Copper-nickel | Include the exact alloy or UNS designation and project requirements. |
Reference note: Copper Development Association copper-nickel guide. Use the project’s approved specification for selection.

- Fitting configuration
Product type, sizes, wall thicknesses and applicable dimensional standard.
- Project conditions
Relevant service information and the approved material specification.

Manufacturing condition, tests, certificates and marking requirements.
- Quantity & destination
Item quantities, required date and delivery location.
- Drawing references
Drawing numbers, revisions and any project-specific notes.
COMMON QUESTIONS
Before you specify copper alloys
Are brass, bronze and copper-nickel the same material?
No. They are different alloy families. The enquiry should identify an exact grade and product specification, not just a general copper-alloy description.
Does this page confirm stock or delivery time?
No. Availability and delivery depend on the exact fitting, grade, dimensions, quantity and documentation requirements. These must be confirmed in the quotation.
Which fitting sizes are available in this material?
Send the required fitting type, end sizes and wall thicknesses. Availability is reviewed for that combination; a material family does not define a universal size range.
What certificates should I request?
Specify the certificate type, material traceability, inspection and testing required by the project. Include supplementary requirements with the initial enquiry.
