Aluminium Alloy 2014 is a high-strength aluminium-copper alloy used for structural and heavily loaded applications where strength is important.
Responds to heat treatment and ageing for high mechanical strength.
Offers useful machining performance for a high-strength alloy.
Formability is better in softer tempers and decreases as strength increases.
Often selected for highly loaded fabricated and machined components.
Aluminium Alloy 2014 is selected for applications that match its specific strength, corrosion, forming, machining and service characteristics.
Used for selected structural and machined aerospace components.
Suitable for highly loaded mechanical parts.
Used in selected high-strength automotive components.
Suitable for strong, precision-machined parts.
Specify the required solution treatment and temper because strength varies significantly with heat treatment.
Copper-bearing alloys generally require more attention to corrosion protection than 5xxx grades.
Evaluate welding carefully; post-weld strength loss can be significant in heat-treatable alloys.
The commonly listed Werkstoff / EN cross-reference for Aluminium Alloy 2014 is 3.1255. Treat this as a grade comparison, not a guarantee of interchangeability. Verify chemistry, product form, condition and governing specification against the supplier certificate before substitution.
Yes. It is a precipitation-hardening aluminium alloy.
It has moderate corrosion resistance and often benefits from appropriate surface protection in demanding environments.
Typical uses include aerospace and heavy-duty structures, automotive components and high-strength machined parts.
