Which brass alloy is right for your application? Six industry-specific guides to help you specify correctly the first time.
Use this table to quickly identify which alloy families apply to your primary design constraint.
| Primary Requirement | Recommended Alloy(s) | Why | Industry |
|---|---|---|---|
| Maximum machinability | CW617N, CW614N | 100% and 95% machinability — lowest cycle times | Industrial, Automotive |
| Potable water (EU/UK) | CW724R | DZR + RoHS free + WRAS/KIWA/DVGW approvable | Plumbing |
| Potable water (US/Canada) | C6802 | NSF 61 certified, AB 1953 compliant, DZR | Plumbing |
| RoHS free + machinable | CW724R, C27450 | Lead ≤0.10%, no exemption, CNC-capable | Electrical, Automotive |
| Maximum conductivity | C11000 | ≥100% IACS — only viable choice for busbars | Electrical, Renewable |
| Cold forming / deep draw | CuZn37 (CW508L) | Alpha-phase only, ≥45% elongation | Automotive, Electrical |
| Hot forging (RoHS exempt) | CW617N, CW614N | Excellent hot workability, Pb lubricates grain boundaries | Industrial, HVAC |
| Hot forging (RoHS free) | CW510L, CW724R | Lead-free forging grades | Plumbing, Electrical |
| High strength | CW724R, CW614N R430 | CW724R: Rm 450–600 MPa; higher temper leaded grades | Industrial, Automotive |
| Refrigerant compatibility | CW617N, CW625N | Proven track record in HVAC/R systems | HVAC |
| Marine / outdoor | CuZn40, CW602N | DZ-resistant options; architectural-grade alloys | Industrial |
| Renewable energy systems | C11000, CW724R | Conductivity (C11000) or corrosion resistance (CW724R) | Renewable Energy |
