ASTM B111 C70600 Seamless Copper Alloy Tubes for Heat Exchangers Boilers Marine Systems
C70600 (CuNi10Fe1.6Mn) is a copper-nickel alloy with superior resistance to seawater corrosion and biofouling. Key chemical components include:
| Element | Cu | Ni | Fe | Mn | Zn | Impurities |
|---|---|---|---|---|---|---|
| Content | Bal. | 9.0~11.0% | 1.3~1.7% | 0.5~1.0% | ≤0.5% | ≤0.2% |
| Property | Value |
|---|---|
| Tensile Strength | ≥380 MPa |
| Yield Strength | ≥170 MPa |
| Elongation | ≥25% |
| Hardness | 80~120 |
- Superior Thermal Conductivity: 50 W/m*K (3x higher than stainless steel), ensuring efficient heat transfer.
- Saltwater & Corrosion Resistance: Ideal for marine condensers and desalination plants.
- Anti-Biofouling: Inhibits microbial growth in cooling systems.
- Seamless Manufacturing: Precision cold-drawn process guarantees uniform wall thickness and leak-free performance.
