Chemical Composition
The chemical composition of C72200 Nickel-White Copper is as follows:
| Element | Symbol | Minimum (%) | Maximum (%) | Note / Function |
|---|---|---|---|---|
| Copper | Cu | Balance | Remainder. Forms the base of the alloy. | |
| Nickel (+Cobalt) | Ni + Co | 14.0 | 16.0 | Primary alloying element. Provides strength and excellent corrosion resistance in seawater. Cobalt is counted as nickel. |

Packaging and shipping
GNEE offers professional packaging for exported copper pipes. First, we apply anti-rust oil and plastic film to prevent oxidation. Then, we securely strap with steel straps and add corner protectors. Finally, we place the pipes on wooden pallets and reinforce them with iron or wooden boxes, ensuring they are moisture-proof and impact-resistant during ocean transport, while facilitating easy loading and unloading. All packaging meets export standards.
