FAQ
Q1: Is C69300 completely lead-free?
Yes. Pb ≤ 0.09%, meeting NSF 372 and global potable water regulations.
Q2: What is the difference between C69300 and C37700?
| Grade | Lead Content | Main Use | Key Feature |
|---|---|---|---|
| C37700 | 1.6–2.5% Pb | Forging | Good machinability |
| C69300 | ≤0.09% Pb | Drinking water | Lead-free + DZR |
Q3: Is C69300 suitable for high-pressure forged parts?
Yes. Its high strength makes it ideal for valves, connectors, and precision forging applications.
Q4: How does C69300 perform in machining?
Machinability is excellent due to silicon additions, although slightly lower than C36000 free-cutting brass.
Q5: What certifications can you provide?
EN10204 3.1 mill test report
NSF-related compliance (if required)
SGS mechanical & chemical test report
Customized material certifications
Q6: Does C69300 resist dezincification?
Yes. C69300 is classified as a DZR (dezincification-resistant) brass, suitable for aggressive water environments.
Q7: Can you produce C69300 according to drawings?
Yes. OEM forging, CNC machining, and custom-shaped profiles are available.
