Identify copper nickel vs nickel silver before ordering.
Copper nickel vs nickel silver
Hypothetical purchase: a customer requests C70600 bar; a vendor offers C77000 instead.
CDA lists C70600 under copper-nickel and C77000 under copper-nickel-zinc (nickel silver).

Order
Ask the vendor to clarify its reply. An alternative offer is a proposal; the customer decides whether to change the request.
Record the customer’s choice before placing the order. Keep the accepted description separate from proposals still under consideration.
Send revised material and cut-piece requirements to the original saw provider after any customer-approved change.
Ask which enquiry version the equipment quotation covers; do not assume that an earlier response addresses a later revision.


Discuss
Contact Jiurun with the identified material, actual supplied form and required cut pieces to discuss the proposed circular-saw configuration.
