- Supply to international standards such as ASTM B36, JIS H3100 and EN 12163
Key Physical Properties
Typical physical and mechanical properties of brass (based on H62/H65).
| Property | H62 value | H65 value | Unit | Notes |
|---|---|---|---|---|
| Density | 8.43 – 8.50 | 8.47 – 8.53 | g/cm³ | Varies with zinc content |
| Electrical conductivity | ~27% IACS | ~27% IACS | % IACS | Lower than pure copper but acceptable |
| Thermal conductivity | 109 – 117 | 111 – 119 | W/(m·K) | Moderate thermal conductivity |
| Melting point | 905 – 925 | 915 – 935 | °C | Solid-liquid range |
| Tensile strength (M) | ≥290 | ≥270 | MPa | Soft annealed temper |
| Tensile strength (Y) | 420 – 550 | 380 – 500 | MPa | Hard cold-worked temper |
| Elongation (M) | ≥40 – 50% | ≥45 – 55% | % | Ductility in soft temper |
| Hardness (HV) | 80 – 150 | 70 – 130 | HV | Varies with temper |
| Machinability | td>Good | Good | — | HPb59-1 is best |
