Know Your C377 Brass Before Releasing the Blank
For C37700 forging, separate the purchased stock requirement from the finished component drawing. A forging brass name does not establish pressure integrity, final tolerance or suitability for a regulated application.

Answers Before You Specify C377
Why forge C377 brass before machining?
A reviewed near-net blank can place material around the required ports and mounting features before final cutting. Compare the tooling, allowance, quantities and final drawing; no universal material-saving or cost percentage is promised.
Is C377 brass lead free?
The selected CDA C37700 reference contains 1.5–2.5% lead. Do not describe this grade as lead-free or infer compliance from its common name. Define the application and required evidence before ordering.
Can C377 brass be used for drinking water?
Grade alone does not establish potable-water suitability or product certification. Identify destination, wetted location, complete product and required approvals; review the actual permitted material and product evidence before accepting the application.
C377 vs C360 brass: what should your drawing decide?
Compare chemistry, stock form, forging route, final features and service requirements. A relative machinability rating does not approve substitution or predict the quoted cycle time.
C377 vs C260 brass: can I use the same route?
Do not assume the same route. C377 is a forging-brass reference; C260 is commonly reviewed for cold-formed sheet components. Confirm full specification and finished function with the drawing authority.
How much does C377 brass forging cost?
Your C377 brass forging quote depends on die and setup scope, usable blank, machining allowance, ports, sealing faces, sample and repeat quantities, finish and receiving evidence. Compare the same final drawing and accepted route.
What should custom C377 brass forgings documentation include?
Identify the controlled final drawing, blank requirement, lot traceability, material documents and first-sample acceptance. Any pressure testing or other application-specific verification needs its own agreed procedure and report scope.
What does a C377 brass forging temperature reference establish?
It supports a supplier process review, not a qualified recipe for every part. Agree the actual billet, geometry, heating route and final acceptance with the responsible supplier before production.
