General Information
| Category | Details |
|---|---|
| Overview | The addition of Cu permits the formation of age-hardening precipitates. The 2xx.x series has the lowest corrosion resistance but the highest strength of the series. |
| Strengths | Moderately high strength (highest of casting alloys). Excellent ductility can be achieved by controlling impurity levels. |
| Limitations | Poorest corrosion resistance of the aluminum alloys, medium to poor impact resistance, and poor castability. |
| Designation | 2xx.x series |
| Typical Uses | Aircraft, automotive applications/engines |
| General Information: Cast Aluminum Alloy: 2xx.x Series (Cu-Alloyed) |
Composition Overview
| Category | Details |
|---|---|
| Compositional Summary | Al/4-5Cu with varying additions of Mn, Mg, Si, Ti, Fe, Zn |
| Material Family | Metal (non-ferrous) |
| Base Material | Al (Aluminum) |
| Effect of Composition | – Cu addition permits age-hardening precipitates. – Mg (0.5%) improves corrosion resistance. – Ag accelerates aging response and reduces stress corrosion risk. |
