Aluminum 2017A AU4G
Aluminum 2017 A, also known as Duralumin, is a high-strength aluminum alloy. Its main composition includes aluminum with copper (3.5-4.5%), magnesium (0.4-1.0%), and manganese (0.4-1.0%).
Main characteristics:
- Excellent mechanical strength
- Good machinability
- Moderate corrosion resistance
- Relatively low density (approximately 2.79 g/cm³)
2017 A is valued for its strength-to-weight ratio.ids avantageux, mais nécessite souvent un traitement de surface pour améliorer sa résistance à la corrosion.
