2XXX series alloys contain copper as the main alloying element, often in combination with magnesium and silicon.
Strength:
Strength is developed through solution treatment and natural ageing (T351, T451) or artificial age hardening (T651, T851). Strength levels in the naturally aged alloys may be further increased by artificial ageing, but this reduces fatigue properties and toughness.
Welding:
With the exception of a few specialised alloys the 2XXX series alloys are not generally weldable by fusion welding.
Corrosion:
2XXX alloys are susceptible to corrosion and may be require protective surface treatments such as anodising or painting.
2XXX alloys are generally used where good levels of strength and toughness are required. The most widely used alloys in this series are 2014A, 2017A and 2024.
Applications include:
Machined parts
Truck wheels
Load cells
2xxx series alloys technical data
| STANDARD DIMENSIONAL AVAILABILITY | |
| Alcoa Europe only supply plate that exceeds the 2014/2014A, 2017A AND 2024 2014 and 2014A are commonly supplied in the T651 2017A and 2024 are characterised by high levels of |
| FORMABILITY | |
| Radii expressed as thickness (t) are minimum recommended for bending plates in a standard press brake with air bend dies. Minimum permissible radii will also vary with design and condition of tooling. Forming over smaller radii is possible immediately after solution heat treatment and quenching. |
| Advice and further details on Alcoa's specialised alloys is available on request. |
