Professional FAQ (Advanced)
Q1: How does C37000 differ from C36000 and C37700?
C36000: Excellent machinability, lower mechanical strength.
C37700: Excellent forging brass, moderate machinability.
C37000: Balances higher strength with good machinability, ideal for forged and CNC-machined components.
Q2: Is C37000 suitable for potable water systems?
No. Due to lead content (0.8–1.8%), C37000 may not comply with NSF/ANSI 61, RoHS, or EU drinking-water regulations.
For lead-free or DZR applications, consider C69300, C46500, or C87850.
Q3: Can C37000 be hot forged for valve bodies and fittings?
Yes. C37000 has excellent hot-workability, maintaining plastic flow, stable dimensions, and reduced scrap in high-volume forging.
Q4: How is the machinability of C37000 compared to C36000?
Machinability is slightly lower than C36000 Free-Cutting Brass, but with proper tooling, lubrication, and feed rates, it produces clean chips and high surface finish.
Q5: Does C37000 resist dezincification?
C37000 has moderate dezincification resistance, sufficient for general plumbing and industrial applications.
For aggressive water environments, alloys like C35330 or C37710 are recommended.
Q6: Do you supply C37000 as finished forged or machined parts?
Yes. Services include:
CNC turning and milling
Drilling, threading, polishing
