Copper & Brass.
Copper and copper-alloy products sourced around conductivity, corrosion, forming, machinability, heat transfer and alloy designation.
Identify grade and condition together.
Designations are preliminary cross-references for enquiry routing. The governing product specification, exact grade designation, condition or temper, dimensions and application requirements must be stated together.

Grade alone is not enough.
Condition, heat treatment, product form, dimensions, surface, corrosion testing, mechanical properties, NDE, traceability and documentation can materially change the supply route.
Bhansali reviews the requirement and coordinates supplier qualification, QA/QC, independent laboratory verification and third-party inspection where required.
