Chemical Composition of C72200 Copper-Nickel Alloy (UNS C72200)
C72200 is a copper-nickel alloy with a nominal 15% Nickel content, often referred to as CuNi15. Its composition is critical for achieving its renowned corrosion resistance, especially in marine environments.
| 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. |
| Iron | Fe | 0.25 | 0.75 | Essential element. Enhances resistance to impingement corrosion and erosion. Improves overall strength. |
| Manganese | Mn | 0.20 | 0.80 | Acts as a deoxidizer during melting, improves castability and workability. |
| Lead | Pb | - | 0.01 | Impurity. Strictly limited as it can cause hot shortness and reduce weldability. |
| Zinc | Zn | - | 0.20 | Impurity. |
| Carbon | C | - | 0.05 | Impurity. |
| Phosphorus | P | - | 0.01 | Impurity. |
| Sulfur | S | - | 0.01 | Impurity. |
| Other Impurities | - | - | 0.30 | Total of all other unnamed elements. |
C72200 nickel-nickel-nickel-copper alloy is an important nonferrous alloy, attracting considerable attention for its unique properties and wide range of applications. Primarily composed of copper, nickel, and other trace elements, it exhibits high strength, high conductivity, excellent corrosion resistance, and superior processability.
C72200 nickel-nickel-copper alloy exhibits excellent mechanical properties. Its strength exceeds that of ordinary copper and it maintains excellent stability at higher temperatures. Its excellent ductility and toughness also enable it to undergo a variety of complex processing operations, such as bending, stretching, and deep drawing. These properties make C72200 nickel-nickel-copper alloy an ideal choice for manufacturing components requiring high precision, high strength, and high reliability.
C72200 nickel-nickel silver has excellent electrical conductivity. Since copper is one of the most conductive metals, the addition of nickel further enhances its conductivity. This makes C72200 nickel-nickel silver widely used in electrical, electronic, and communications applications. It can be used to manufacture electrical components such as conductive sheets, conductive tubes, and brushes, as well as conductive materials such as wire and cable.
C72200 nickel-nickel silver also exhibits excellent corrosion resistance. The addition of nickel ensures its stability in harsh environments such as air and seawater, making it less susceptible to corrosion and oxidation. Therefore, C72200 nickel-nickel silver is widely used in the shipbuilding, chemical, and marine engineering sectors.
