4. About the Environmental Issues of C3604 Free-Cutting Copper and Its Substitute Products
Our company extensively uses C3604 as a raw material. Given that some users may not have a clear understanding of the “environmental” concept regarding this material, we provide the following explanation:
| Alloy Type | Lead Content (Weight %) | Notes |
|---|---|---|
| C3604 | 2.8 – 3.7% | Standard brass used unless specified otherwise. |
| Lead-free Copper | Less than 0.01% | Available upon request for higher standards. |
| C3602 | Approx. 2.5% | Another commonly used brass type. |
| H59-1 | Approx. 4.0% | Higher lead content; suitable for specific applications. |
| H62 | Approx. 3.5% | Good mechanical properties, commonly used in fittings. |
| Red Copper | Negligible | Excellent conductivity, used in electrical applications. |
The difference in raw material prices and processing characteristics of these materials leads to different product pricing. The lead-free copper option is generally more expensive than C3604. Please specify if you require the second standard lead-free copper to avoid any misunderstandings in the future.
