Specification-led brass supply
Copper-nickel 95/5 and UNS C71640 appear in specialist project requirements, but the names do not define one interchangeable alloy. Each enquiry must preserve the exact designation in the buyer specification.
Because product form, chemistry, condition and acceptance criteria may differ, Indigo reviews these requirements against the governing standard or approved project data sheet before quotation.
A clearer route to purchase
Write the UNS or EN grade and product standard on the enquiry.
State OD or nominal size, wall, length, tolerances and form.
Identify MTC, examination, marking and inspection before quotation.
Use the 3D builder to organise the product and purchasing data.
Technical specification
Use this summary to prepare the enquiry. The accepted quotation, purchase specification and current governing-standard edition control the order.
Published ranges are enquiry references, not a live-stock promise. Confirm each size, temper, test and document in the supplier’s written quotation.

Before requesting a quotation
Do not assume they are the same. Preserve the exact alloy designation and governing specification from the approved project documents.
Specialist products must be reviewed by alloy, product form and governing standard. A generic range could create an unsafe or unquotable substitution.
Attach the material data sheet, standard and edition, drawing, dimensions, tolerances, quantity, test plan and inspection requirements.
Only as a clearly identified alternative subject to written approval by the responsible engineer or end user.
