The difference between purple copper and brass
| Characteristics | Purple Copper | Brass |
| Composition | Pure copper (Cu ≥ 99.9%) | copper zinc alloy (Zn 5% -45%) |
| Strength | Low(200-250 MPa) | High(300-500 MPa) |
| Hardness | Low (40-100 HB) | High(60-200 HB) |
| Ductility | Excellent | Good |
| Conductivity | Excellent(close to 100% IACS) | Low(20% -60% IACS) |
| Thermal conductivity | Excellent(401 W/(m · K)) | Low (120 W/(m · K)) |
| Corrosion resistance | Good(easy to form copper green) | Good(easy to remove zinc corrosion) |
| Machinability | easy to stick tool | especially lead containing brass |
| Appearance | Purple red | golden yellow |
Detailed Field Applications
